2. In the terminology, a function f(x) is even when its graph is symmetric with respect to the y-axis, and odd when its graph is symmetric with respect to the origin. Prove that (a) f(x) = a,,xr+. 2n+1 .+a,x' +a,x is an odd function. (b) f(x) = a,x +a,-x-, +.+a,x +a, is an odd function. (c) The product of two even (or two odd) function is even. (d) The product of an odd function and an even function is odd.
