Provide an appropriate response.Suppose that f is a polynomial function of degree 4. If -8 and 13 are zeros of f and the graph of f is symmetric with respect to the y-axis, write f(x) in factored form.
A. f(x) = (x + 8)2(x - 13)2 B. f(x) = (x - 8)2(x + 13)2 C. f(x) = (x + 8)(x - 13)(x - 8)(x + 13) D. f(x) = (x + 8)(x - 13)
