We say f : R –→ R is even if f(-x) = f(x) for all x. We say f is odd if f(-x) = -f(x) for all x. (a) Prove that if f is even and differentiable then f' is odd. Demonstrate this result graphically using a generic example function. (b) Prove that if f is odd and differentiable then f' is even. Demonstrate this result graphically using a generic example function.
