Section 6.1 (Sullivan, 8th ed.) MAC1140, MAC11476-1: Composite FunctionsA composite function is obtained by substituting one function into another function;(f g)(x) = f(g(x)), read f composed with g(x), means that every x in function f isreplaced with the g function. To evaluate a composite function, (f g)(n), evaluatefunction g for n, then evaluation function f for g(n).[1]x -3-2 -1 0 1 2 3 Find:f(x)119 7 5 3 1 -1(f g)(1)g(x)-8-3 0 1 0 -3 -8(g f)(3)2.
