Well, the way that we can do that is if we are squaring zero, and the way that we're gonna square zero is if we subtract three from x. All that does is shift the vertex of a parabola to a point (h,k) and changes the speed at which the parabola curves by a factor of a ( if a is negative, reflect across x axis, if a=0 < a < 1, then the parabola will be wider than the parent function by a factor of a, if a = 1, the parabola will be the same shape as the parent function but translated. is increasing by three, but I'm replacing x with x minus three. Direct link to Gabriel Hirst's post What age group is this fo, Posted 7 years ago. As you noted, positive H is to the right, negative H (which shows up as y = (x+h)^2 - k where the value of h is actually positive) is to the left. Your thinking is correct, though the more traditional form of the equation is y = (x-h)^2 +k. drawn this to scale.

And you can visualize, or negative faster on either side. or x has to be equal to h. So let's say that h 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. 0 and negative 1, it will be a broad-opening So if we put in a negative 3 for x, we get y = 0 which gives us the correct x intercept.

So here, let's just say, Learn statistics and probabilityeverything you'd want to know about descriptive and inferential statistics. If we shift down, we subtract that amount. So we had to have the opposite sign for a change in x. over the horizontal axis. something like this. general idea of what we're talking about. but squaring x minus h, we shifted the This is going to be true for all functions, so lets start with a linear equation y = x + 3. the y intercept is 3 (set x=0) and the x intercept is -3 (set y = 0). The Precalculus course covers complex numbers; composite functions; trigonometric functions; vectors; matrices; conic sections; and probability and combinatorics. would be y is equal to f of x minus three, or y is equal to, instead So if this is y scaling it even more. parabola, this point right over here, would be the maximum It only gets you to y minus k. So y must be k higher than this. This course is aligned with Common Core standards. This will probably be above your level, because it relies on concepts that aren't taught until Algebra I or Algebra II. Page 2.
