Create 2 functions named f(x) and g(x). Define the following and give an example using real number values: a. Sum function b. Difference function c. Product function d. Quotient function e. Composite function f(g(x)) f. Composite function g(f(x)) For instance, if f(x)=3x and g(x)=x-1, then for the sum function: (f+g)(x) = 3x + x-1 = 4x-1 (f+g)(2) = 4(2)-1 = 8-1= 7
