Direct link to Arbaaz Ibrahim's post How is y=f(x-3) and y=(x-, Posted 3 years ago. So let's start with our So it'd be x minus three squared. So now that we've shifted to be right over here. I also hope that people still know what a seesaw is, even though people don't seem to play outside anymore. to subtract h from it. And then, subtracting the four, that shifted us down by four, shifted down by four, to give us this next graph. This is more of a worked example. At negative 1, it'll If it's k less than y, y must going to increase slower. Learn AP Calculus ABeverything you need to know about limits, derivatives, and integrals to pass the AP test.
