The second derivative has already been found and factored to be f"(x) = (5x)(x+2). Use interval testing to find where the function f(x) is concave upward or concave downward. concave upward on (-∞, -2) U (-2,5); concave downward on (5,00) concave upward on (-2,5); concave downward on (-∞, -2) U (5,00) concave upward on (-∞, -2) U (5, 00); concave downward on (-2,5) concave upward on (5, 00); never concave downward never concave upward; concave downward on (-∞0, ∞0)
