Given the following absolute value function find the range. ƒ(x) = |x + 5| - 8

a) range: [5,∞)
b) range: [-5,∞)
c) range: [-8,∞)
d) range: [8,∞)

The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0. 

Tacking on "-8" to |x+5| leads to |x+5|-8

The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|

Final choice C)

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
