Types of Graphs (Cambridge International IGCSE Maths): Exam Questions

Match the graphs to the equations.

(1)$y=\frac{1}{2}x+3$, (2)$y=2^{x}$, (3)$y=-2.1x^{3}$,

(4)$y=\frac{3}{x}$, (5)$y=-2x^{2}+3x+1$

The equation of a curve is $y=(x--1)^{2}--6$

Write down the coordinates of the turning point.

Sketch the graph of $y=3^{x}$* *

Give the value of the $y$-intercept.

Write down the equation of the line of symmetry of the graph with equation $y = ( x - 2 ) ( x + 2 )$.

On the diagram, sketch the graph of $y = ( x + 1 ) ( x - 3 )^{2}$.

Label the values where the graph meets the $x$-axis and the $y$-axis.

Sketch the graph of the function.

$y=\frac{1}{x}$

The diagrams A, B, C, D, E and F are six graphs of different functions.

Complete the table to identify the correct graph for each function. One has been done for you.

$f(x)=x(x+2)(x--3)$

On the diagram, sketch the graph of $y=f(x)$for – 3 less-than or slanted equal to x less-than or slanted equal to 4. Show the values of the intersections with the axes.
