What is f of 2? Now, this won't always be the limit even if it's defined, but it's a good place to start just to see if something reasonable could pop out. So looking at it this way, if we just evaluate f of 2, on our numerator we're going to get 2 squared plus 2 minus 6. So that's going to be 4 plus 2, which is 6, minus 6. You're going to get 0 in the numerator, and you're going to get 0 in the denominator. So we don't have the function is not defined. So not defined at x is equal to 2. f not defined.
