Khan Academy's Algebra 1 course is built to deliver a comprehensive, illuminating, engaging, and Common Core aligned experience! You typically won't see Because f(2) = 9, we need to compensate for adding the 3 by defining g(x) = f(x-3), so that g(5) = f(2) = 9. x is, g of x-- no matter what x we pick-- g of x Direct link to Rashel's post f(x)=|x|-3.
