Find the following limits for graphed above.

  1. What y-value does approach as approaches from the positive (right) side?

  1. What -value does approach as approaches from the negative (left) side?

  1. What value does approach as x approaches from both sides?

    Since a limit is a predicted -value, it can exist at a hole.

  1. A two-sided limit must agree from both sides.
