Question

Verify that f and g are inverse functions.
f(x)=4x^2, x greater and equal to 0; g(x)=√x/2

Answer 1

u begin by makeing f(x)=4x^2 into y=4x^2.
then u swap x and y making it x=4y^2.
then u begin solving for y

Answer 2

\[y^2 = x/4 \]
\[ y = \sqrt{x/4} = \sqrt{x}/2 \]
therefore f(x) and g(x) are inverses

Answer 3

i dont get that
