Answer:
The range is just the y-values that result from plugging in the given x-values.
Meaning, if x = -3, y = f(-3) = 2(-3)+3 = -3
So the first value in your range is -3.
Now plug in (-1)
y = f(-1) = 2(-1)+3 = 1
The next value in your range is 1
Plug in the 1.
y = f(1) = 2(1) + 3 = 5
The last value in your range is 5
