ie: As x (arrow) -3, f(x) (arrow) ?.

Question

This is the actual question. The others are just like it. Once answered, we are to graph it. I have no idea how to do this.
Thanks.

Answer 1

We can't tell you want f(x) approaches as x approaches 3, unless you tell us what function f(x) is. The arrow signifies "approaches"

Answer 2

I don't know what function f(x) is. This instructor is brief with her notes, and the book is very unhelpful. I guessed at the practice problems.
