Can someone show me how to solve this?
Prove limit[x^3, x, 2]=8
First of all, I have no idea what CAS speak is. Second, all the information I have is what I wrote. I am taking this as a correspondence course so I have no professor and write things the way I see them. I'm sorry if I'm doing something wrong. There are no calculus classes anywhere near me that I can take and this is my only way. This is a required class or I would not even be taking it in the first place.
