Calculus POD #3 Simplify the Following Expression [f(7+h)-f(7)] / h given that f(x) = x^2 + 49

For the third Calculus 1 Problem of the Day, we're still looking at some review material. This is a precalculus or college algebra problem that looks a lot like an average rate of change problem that we'll be working on in calculus in a few short days. We're using function notation to simplify the expression [f(7+h)-f(7)] / h given that our function is f(x)=x^2 + 49
