1.2.24 Combinations of graph transformations (A-level only)

Card 1 of 23

In a transformation of y=f(x)y=f(x)y=f(x), what do changes outside fff alter?

A

Stretching y=f(x)y=f(x)y=f(x) vertically by factor 2 and then translating up by 1 gives y=2f(x)+1\boxed{y=2f(x)+1}y=2f(x)+1​.

B

The negative output multiplier reflects it in the xxx-axis.

C

Translating y=f(x)y=f(x)y=f(x) up by 1 and then stretching vertically by factor 2 gives y=2f(x)+2\boxed{y=2f(x)+2}y=2f(x)+2​.

D

They alter the output, so change yyy-coordinates.
