The problem is:
Rewrite f(x) = abs(x2) + [2 * abs(x+5)]
I don't even know where to start.
PLEASE HELP!!!!!!

I don't really see a benefit in rewriting it, since it compactly says what the function is in one statement, but you could also write it this way:
When x>2, f(x) = x  2 +2x +10 = 3x + 8
When 5<x<2, f(x) = 2x+2x +10 = x + 12
When 5>x, f(x) = 2x 2x 10 = 3x 8
The function is continuous, but its slope is not
