Please help me out here with this problem:
37. Express the function f(x)=l x l + l x-2 l
without using absolute value signs.
Okay, I've took a sneak peak at the answer key and it is given in kinda of like piece-wise notation where they have 3 equations and different intervals of x for them.
Are you suppose to just take off the signs? [tex] f(x)= 2x-2[/tex] but know I know there is a catch... Does the range still apply or something?
