For what value of the constant c is the function f continuous on (-, )? I'm just sitting here with a face like this ---> Do I need to factor something? Or rationalize?

For f to be continuous it needs to not have any jumps in it. Especially at x=2. So you want to find c so that (by sticking x=2 into both the parts of that equation and making them equal).
nice, that’s really cleary explained Matt +1 rep from me
