Suppose an odd function f has an inverse g. Prove that g is also odd.

f(x) = f(x)
x = g(y)
x = g(y) but x = (g(y)) = g(y)
so, g is odd

If f and g are functions defined for all real numbers, and f is an odd function, then f ∘ g is also an odd function. Justify. I wrote false cause for example if f = x^3(odd) and g=x^2(even) the fog is even.
