Question

I need help with finding the limit for problem #1. I've already solved 2-4 I just don't get the first one.

Answer 1

Answer: 9

-------------------------------------------

Look at the graph of f(x). Locate x = 3 on the graph and move to the left of that location. If you get closer and closer to x = 3 from the left side, then you approach y = 3

Do the same for g(x) as well. If you approach x = 3 from the left, then you approach y = 3. It does not matter there is a discontinuity here as we're only worried about approaching x = 3 from the left and not actually getting to that specific x value. 

We multiply those y values to get 3*3 = 9 as the answer
