Determine where the function f(x) = x + [|x^2|] - [|x|] is continuous
I don't understand how to work this problem. Can someone show and explain how to solve this problem in detail? I've asked for help on this problem before but I still don't understand it.
The function is continuous everywhere but 0. I don't understand how to get that answer or what method is used to arrive to that conclusion.
Continuity is investigated.
