2-130.

A function, *f*, is *continuous* for all real numbers. If*x* ≠ −3, then what must *f*(−3) equal? Write a piecewise function that represents this situation. Homework Help ✎

After factoring, you will see that there is a hole (not a vertical asymptote) at *x* = −3.

While *f*(−3) does not exist, the

exist, and gives us the *y*-value of the hole.
