Question

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

f(x) equals 4/x. and g(x) equals 4/x

Answer 1

Hint:
\[f(x) = \frac{4}{x}\]
\[f(g(x)) = \frac{4}{g(x)}\]

Answer 2

uh... Im sorry. I still dont really understand

Answer 3

g(x) = 4/x, so wouldnt what you put be like, 4/4/x/4/x????

Answer 4

Actually, \(\dfrac{4}{\dfrac{4}{x}} = 4 \div \dfrac{4}{x} = 4 \times \dfrac{x}{4} = x\)
