Question

Give an example of a combination of two functions, f(x ) and g(x), that would result in a rational function. Be sure to identify the function type for f(x) and g(x ), as well as the operation used to combine them.

Answer 1

Explanation:

In the following examples, let f(x) = 5x+2 and g(x) = x2-1. We will then evaluate each combination at the point x=4. f(4)=5(4)+2=22 and g(4)=42-1=15
