Learning how to draw the graphs of functions is an important skill in Year 10 Mathematics.
In this post, we will look at how to draw three types of functions: linear, quadratic, and cubic.
Let’s break it down so it’s easy to understand!
Linear functions look like straight lines. They follow the formula (y = mx + c), where:
What to Know:
Example: For the function (y = 2x + 1):
How to Draw It:
Quadratic functions look like a U-shape. Their formula is (y = ax^2 + bx + c).
What to Know:
Example: For the function (y = x^2 - 4):
How to Draw It:
Cubic functions can look more complicated. They follow the formula (y = ax^3 + bx^2 + cx + d).
What to Know:
Example: For (y = x^3 - 3x):
How to Draw It:
By understanding the key points of linear, quadratic, and cubic functions, you can draw their graphs accurately.
Make sure to look for important points like intercepts, vertices, and turning points when you draw.
Practice with different functions to get better at sketching!
