If h(x) = x – 7 and g(x) = x2, which expression is equivalent to(g*h)(5)? a (5 – 7)2,
b (5)2 – 7, c (5)2(5 – 7), d (5 – 7)x2

(g*h) (5) means the product of the two functions, h(x) and g(x), evaluated at x = 5. g(x) = x^2 and h(x) = x - 7 The product of h(x) and g(x) is (x-7) * x^2 Replacing 5 for x => (5-7)(5)^2. That is the option C) (5)^2 (5-7). C (5)^2 (5 - 7)
