f(x) = x2. What is g(x)?

Answer

g(x) = (1/3 x)^2

Explanation

The original point was 1,1 in the f(x) function.

The transformed point is 3,1 in the g(x) function.

So the x value has been multiplied by 3.

This means g(x) = (1/3x)^2

It has to be in the brackets as it involves the stretch of the x value not the y value.

It’s also 1/3 because if it is in the inner brackets then it does the opposite to x so

x / 1/3 = 3x
