What's the range of the function of f(x) = -4x -8 for the domain

Thus the overall range is all real numbers

r = (-∞, ∞)

Explanation:

The domain is all possible input values for x

Since there are no restrictions on x the domain is

all real numbers.   d = (-∞, ∞)

The range is all possible output values for f(x)

Note that as x gets larger in the positive direction,

f(x) gets larger in the negative direction ... f(x) → -∞

As x gets larger in the negative direction,

f(x) gets larger in the positive direction ... f(x) → ∞

Thus the overall range is all real numbers

r = (-∞, ∞)

d is the correct answer
