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. So there's no simple thing there. Even if this did evaluate, if it was a continuous function, then actually the limit would be whatever the function is, but that doesn't necessarily mean the case. But we see very clearly that the function is not defined here.
