Or I should say greater We can think graphs of absolute value and quadratic functions as transformations of the parent functions |x| and x. So when x equals three, instead Think about what happens Importantly, we can extend this idea to include transformations of any function whatsoever! the trick is just internalizing what is inside and what is outside the function. A quadratic function is in what shape? Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you.
