(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Write f(x) = |x^{2}-x-12| as a piecewise function.

2. Relevant equations

3. The attempt at a solution

-x^{2}+x+12 where x>^{1}/_{2}

x^{2}-x-12 where x[itex]\geq[/itex]0

According to the answer book the answers are

-x^{2}+x+12 where -3<x<4

x^{2}-x-12 where x[itex]\geq[/itex]4

2x^{2}-5x-3, x[itex]\leq[/itex]^{1}/_{2}

I am really bad at functions when it comes to domain and range..

Help please!
