Question: In problem 1-4, state whether the indicated function is continuous at 3. If it is not continuous, tell why. 1. f(x) = (x - 3)

In problem 1-4, state whether the indicated function is continuous at 3. If it is not continuous, tell why.
1. f(x) = (x - 3) (x - 4)
2. g(x) = x2 - 9
3. h(x) = 3/x - 3
4. g(t) = √t - 4
