Answer:

(d) {-7, -2, 11, 20}

Explanation:

You can put the domain values into the function and evaluate to find the corresponding range values. Here, we'll do them "all at once."

y = 3{-4, -1, 2, 5} +5

= {-12, -3, 6, 15} +5

= {-7, 2, 11, 20} . . . . . matches choice d

_____

To save yourself some arithmetic, you can observe that the answer choices differ in the 2nd and 4th values, so you only need to evaluate the function for x=-1 or x=5 to determine the correct answer choice.
