Can you please solve the question 9.3.16 ?

Exercise 9.3.16 A function f: R R is called symmetric if f(x) = f(-x) for all x E R. Let W be the subset of FuncR,R consisting of all symmetric functions. Is W a subspace of FuncR,R? Exercise 9.3.17 A function f: R→ R is said to vanish at infinity if limx→∞ f (x) = 0 and limx→∞ f (x) = 0. Let W be the subset of FuncR.R consisting of all functions that vanish at infinity. Prove that W is a subspace of Funcm m
