Translations are often confusing at first glance. point, it had the effect of shifting up the y value by k. And that's actually true shifting a parabola, I like to look for a distinctive point. You can use transformations of quadratic functions to analyze changes in braking distance. If you have something like (x-5)^2 + 3, that negative shifts to the right because you need to have x=5 for the inside of parentheses to be 0 (5-5)^2 and if you have (x + 4)^2 - 3, you need to have x=-4 to had to have it be 0 because (-4+4)^2=0. Our mission is to provide a free, world-class education to anyone, anywhere. We've seen linear and exponential functions, and now we're ready for quadratic functions. We shifted it to the right.
