We're just going to plug in these numbers
so for -2
f(-2) = 4-5 = -1
f(-1) = 2-5 = -3
f(1) = -2-5 = -7
f(2) = -4 - 5 = -9

(-1,-3,-7,-9)

The domain: {-2;-1; 1; 2}

f(x) = -2x - 5

subtitute the values of x to the equation:

f(-2) = -2(-2) - 5 = 4 - 5 = -1
f(-1) = -2(-1) - 5 = 2 - 5 = -3
f(1) = -2(1) - 5 = -2 - 5 = -7
f(2) = -2(2) - 5 = -4 - 5 = -9

Answer: The range: {-9;-7;-3;-1}.
