Answer:

  -45, 1, 4, 5, 9

Explanation:

The first argument value, -5, is less than -1, so the first section of the function definition is used. f(-5) = 9(-5) = -45.

The 2nd to 5th argument values are in the interval [-1, 3], so the second section of the function definition is used.

The last argument value, 6, is greater than 3, so the last section of the function definition is used. f(6) = (6 -3)^2 = 9.

Function values are shown in the table attached.
