Good morning from Israel

I'm a first year student learning about function limits.. I need to prove / disprove the following statements which I got a bit tangled up with..



" Prove or disprove with a contradictory example "









Thanks !!
1. The problem statement, all variables and given/known data



2. Relevant equations



3. The attempt at a solution

Now this is calculus math, not precalc

Second, you need to show attempt to solution before you will get help.
