## anonymous 5 years ago Verify that f and g are inverse functions. f(x)=4x^2, x greater and equal to 0; g(x)=√x/2

• This Question is Closed
1. anonymous

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

2. anonymous

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

3. anonymous

i dont get that
