I think that this problems is sorry to say the least. I wants me to take the right and left hand limits, but to my observation the coordinating values are decimals.
Below is the graph and here it asks me, also I have the answers only to those without a question mark
1. The limit as x approaches 0.8 from the left hand side:?
3. The limit as x approaches 0.8 from the right hand side:?
4. Is this function continuous at 0.8 (Y/N): No
