Best ResponseYou've already chosen the best response.1find g(0)... by substituting x = 0 into g(x)... then substitute that answer into f(x0 1. (a) f(g(0)) g(0) = 2 f(2) = 3 x 2  5 = 1 (b) similar to (a) but start with f(0) 2. (a) looks like finding the derivative of f(x) = 3 not sure on the notation (b) find g(3)... then substitute that answer into g(x) again
