1-113.

Let . Evaluate: 

  1. x = 3, so in this case, x ≥ 1. Therefore, use the third piece of the function.

  1. x = −1, so in this case, −2 ≤ x ≤ 1. Therefore, use the second piece of the function.

  1. x = −2, so in this case, −2 ≤ x ≤ 1. Therefore, use the second piece of the function.

  1. See the hint in part (a).
