Learn Algebra 2 aligned to the Eureka Math/EngageNY curriculum polynomials, rational functions, trigonometry, and more. So it does look like we have most classic parabola, y is equal to x squared. And if I focus on the vertex of f, it looks like if I shift that to the right by three, and then if I were to shift that down by four, at least our vertices would overlap. 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. And on a parabola, the vertex is going to be our most distinctive point. Chapter 111 Subchapter C Texas Education Agency. I think Sal is assuming that k is positive, and the same with h.
