1.) What is the average rate of change for the function g(x) for the interval [3, 8]? Show all work.
g(x) = 2x^2 + 4x - 3

2.) The cost per guest of catering an event of no more than 125 people is modeled by the function f(x) = 30 + 10x. The number of guests is modeled by the function g(x) = 125 - x, where x represents the number of guests fewer than 125 that attend. Evaluate (f • g)(32) and interpret what it means in the context of the problem. Show all work.
