1. The problem statement, all variables and given/known data Apologies for any trouble, but I'm not going to post any numbers, as my school is very sensitive about plagiarism and the like in homework. I only need some help in figuring out what to do. I'm given a table of x values 1 to 5, and for each, corresponding y-values for two functions: f(x) and g(x). So my table has three rows x, f(x), and g(x). I have to find the limit of [2f(x) - 3g(x)] as x approaches 1. I can do g(f(x)), but... Af(x) - Bg(x)? What...? I know limits are calculus stuff, but what I really need help with here is manipulating g(x) and f(x), and that should be precalculus... right? 2. Relevant equations None that I know of 3. The attempt at a solution I'm stumped. The first thing that did cross my mind was substituting the y values I'm given from the table into f(x) and g(x), but... that can't be right! I get a number that makes no sense.
