Answer:

Range: {1, 3, 11}

Step-by-step explanation:

To find the range, just substitute the inputs into the function to find the outputs.

f(-2) = 2(-2) + 5

f(-2) = -4 + 5

f(-2) = 1

f(-1) = 2(-1) + 5

f(-1) = -2 + 5

f(-1) = 3

f(3) = 2(3) + 5

f(3) = 6 + 5

f(3) = 11

So the range is: {1, 3, 11}.
