Question

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

f of x equals eight divided by x and g of x equals eight divided by x

Answer 1

answer
f(x)=8/x, g(x)=8/x
f(g(x)) = f(8/x)=8/8/x=x,
g(f(x)) =g(8/x) =8/8/x=x,
so f(g(x)) = g(f(x)) = x. if f of x equals eight divided by x and g of x equals eight divided by x
