Katarina [22]

Answer:

Nine

Step-by-step explanation:

3 dollars for children tickets : x

The graph of the the function f(x) is given below.
MrRissso [65]

Answer:

  • dne
  • 1
  • -4

Step-by-step explanation:

1. As x approaches zero from the right, the line representing f(x) approaches 0. As x approaches zero from the left, the line representing f(x) approaches -4 (this is the answer to the 3rd part). These two limits are different, so the limit as x approaches zero is said to be "does not exist."

2. The line representing f(x) approaches 1 as x approaches 1 from the right. The limit is 1.

3. See 1. above. The limit is -4.
