love your videos. You make learning precalcus easy !! I should pay you instead of my professor

tip: you don't need to solve all 3 regions, just solve the one on the left. once you solve it, then the region to the right will always be the opposite sign of what the first one is and so on

[MathewWuzHere]

You always explain it so well. Awesome tutorials.

[lianhua]

Thank you sooo much you saved me with my math exam! 😭😭
