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."

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
