**Hook: The Mystery of the Vanishing Ice Cream Truck**
Imagine the scene: It's a sweltering afternoon in Singapore, and the familiar jingle of the ice cream truck has suddenly vanished from your neighbourhood. You realise that the truck's route and timing have changed, but you're not sure how or why. You decide to use your secondary math skills to solve this real-world mystery.
**Understanding Functions and Graphs**
*Functions*, our trusty mathematical friends, help us understand how things change. They take inputs (like the time of day) and give us outputs (like the ice cream truck's location). *Graphs* are like maps that show us how these changes happen.
**Domains and Ranges: The Ice Cream Truck's Territory**
The *domain* of a function is like the ice cream truck's service area. It's the set of possible inputs, or in our case, the times when the truck is on the road. For our missing jingle, let's say the domain is from 2 PM to 5 PM.
The *range* is what the function outputs, or the places the truck visits. Let's say our truck visits schools, malls, and housing estates. So, our range is these locations.
*Fun Fact:* The largest ice cream sundae ever made was over 21 feet tall and used over 8,000 scoops of ice cream! (Source: Guinness World Records)
**Intercepts: Where the Truck Starts and Ends**
*Intercepts* are where the graph crosses the axes. They're like the starting and ending points of the ice cream truck's journey. If the truck starts at the void deck of Block 501 at 2 PM (x-intercept), and ends at the playground of Block 401 at 5 PM (y-intercept), we can use these points to trace its route.
**Symmetry: When the Truck's Route Repeats**
Symmetry in graphs shows when a function repeats its behaviour. If our ice cream truck follows the same route every day, its graph would be *symmetric* about the vertical line at x = 3 PM (midpoint of its domain).
*Interesting Fact:* The ice cream cone was invented in 1904 at the World's Fair in St. Louis, Missouri, when an ice cream vendor ran out of dishes and partnered with a waffle vendor to create edible cones. (Source: National Ice Cream Association)

**Imagine you're at Sentosa, and you want to know how high the Singapore Flyer is at any given time. You could measure it every minute, but that's tiring, right? This is where functions and graphs come in, making math as easy as a ride on the S.E.A. Aquarium conveyor belt!
Functions are like magic tricks that take an input (like time) and give you an output (like height). In Singapore's secondary 4 math syllabus, you'll learn about different functions, like linear, quadratic, and exponential. Each has its own 'trick', or formula, to spit out the answer.
"Fun fact: The word 'function' comes from Latin 'functio', meaning 'performance' or 'office'. So, functions are like math performers, each with its unique 'office' or role!"
Graphs are like storybooks that plot functions. They show how the output changes as the input changes. In Singapore's MOE syllabus, you'll learn to plot points, draw lines, and even make predictions using graphs!
"Interesting fact: The first graph was created by Scottish mathematician John Napier in 1614. He called it a 'line of numbers', but we call it a 'line graph' now!"
Now, you've met functions and graphs. But what if you want to know the input given the output? Enter composite and inverse functions!
Composite functions are like teamwork. One function takes the input, another takes the output of the first, and so on. Inverse functions are like detectives. They find the input that gives a specific output, solving the 'case' in reverse.
So, the next time you're at East Coast Park, remember, math is everywhere - in the height of the palm trees, the time it takes for the sunset, or even the number of prata you can eat after a long day!

Functions are like secret recipes, turning inputs (ingredients) into outputs (delicious dishes). Graphs, on the other hand, are the cooking instructions, showing how these inputs and outputs relate to each other.
Fun Fact: The concept of functions and graphs has been around since the 17th century, with mathematicians like René Descartes and Isaac Newton contributing to its development.
In the Secondary 4 Math Syllabus, Singapore, you'll dive deep into graphs, learning to interpret and analyse them. You'll explore:
These graphs are like different cooking methods - grilling, boiling, or frying - each with its unique results.
Algebraic methods are like following a recipe step-by-step. Let's say you have the equation 2x - 5 = 11. To solve for x, you'd follow these steps:
And just like that, you've found your x - the stall with the best char kway teow!
Graphical methods are like using a thermometer to check if your food is cooked. You plot the equation, find the point where the graph crosses the x-axis, and that's your solution!
Interesting Fact: In the 19th century, mathematicians like Carl Gustav Jacob Jacobi and Niels Henrik Abel made significant contributions to solving equations graphically.
But what if you could solve equations without all this math? What if you could 'see' the solution? That's where technology comes in, with graphing calculators and computer software making solving equations a breeze. So, are you ready to become a 'graph master' and solve equations like a pro?
Quadratic functions can model scenarios where there's a constant change in the rate of change. This could be seen in the height of an object thrown in the air, where the rate of change of height decreases over time due to gravity.
Absolute value functions can model real-world scenarios where the direction of change matters but not the magnitude. An example is the distance of a point on a number line from zero.
Real-world scenarios involving linear functions often involve constant rates of change. For example, interpreting the distance traveled by a car as it moves at a constant speed over time.
Symmetry in graphs can represent balance or reciprocity in real-world situations. For example, it could model the balance of payments between two countries, where positive and negative values represent imports and exports respectively.
