Suppose f is an even function and g is an odd function such that the composition fog is defined.d show that fog is an even function

since f(x) is even, f(z) = f(z)
g(x) = g(x) since g is odd
f(g(x)) = f(g(x)) = f(g(x)) so fog is even

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.
