# What is the domain and range of y=abs(x)-4 ?

D: all real values, R: $y \ge - 4$

#### Explanation:

The domain, or possible x values, is All Real Values.

The resultant range:

when $x = 0 , y = - 4$

and if we evaluate values both greater and smaller than 0, y will only get bigger (remember that the negative values of x will be turned to positive by the absolute value sign). And so the range is $y \ge - 4$
