What is the domain and range of f (x) = - 4x-1

Domain: the set of all real numbers. Range: same.

Step-by-step explanation:

f (x) = - 4x - 1 is a polynomial, so its domain is "the set of all real numbers," just as it is for every other polynomial. This being a first-order linear equation, y can take on any real value, and thus the range is ""the set of all real numbers."
