# Math Help - Limit Problems Help

1. ## Limit Problems Help

Hi guys thanks for helping me here's the questions.
1) Evaluate each limit via direct reasoning or an algebraic approach. Where appropriate, use infinity (or -infinity) in your answer.

lim x->2 x+5/x-2

3. Limit doesn't exist because it goes to - infinity when you approach from the left and + infinity when you approach from the right.

I really don't understand how you got that..

5. Evaluate values close to two or do the graph.

I'm stuck on this problem

lim x-> infinity (4x-3)/(7x+8)

Add a constant to the numerator so the fraction divides. Compensate of course by adding a second fraction with the same denominator.
