Question

I need help with these limit problems. I'm having difficulty reading the graphs to find the limits. Can someone help me please?

Answer 1

There is a magnifying glass icon on the graph. If you'd click on that, the graph will be presented in a larger, more readable format.

I agree with your "DNE" response to #1. There's no limit as x approaches 2 from the left, as the graph continues to zigzag up and down; For a limit to exist, the function value must approach one unique limit.
