WebHow would you do this? Shifting f (x) 1 unit right then 2 units down. The equation is f (x)=x^2-2x-1. My book says this to shift 1 unit right its g (x)= (x-1)^2-2 (x-1)-1 =x^2-4x+2 for shift 2 units down h (x)=x^2-2x-1-2 =x^2-2x-3 I need some help understanding this please • ( 2 votes) The Purple Bear 3 years ago WebThe standard parabola can be stretched and compressed with the parameter a a.

WebSay we have the equation: Y-k=x^2. To see how this shifts the parapola up k units, substitute x with 0. The equation will simplify to y-k=0. So for the equation to be true y needs to be … WebThis will reflect the parabola across the x axis. A parabola that opened upward will now open downward, and vice versa. For example, if we have the quadratic f(x) = x 2, then we would multiply by -1 on the right side to get g(x) = -x 2.. This second parabola g(x) = -x 2 has the same shape than the original parabola f(x) = x 2, but it opens downward, and it is reflected … dickson plumbing cambridge

WebIf we start at the vertex (it does not matter where it is on the graph), go over 1 and count how much you go up or down to determine the magnitude. Several examples and for simplicity's sake, keep the vertex at the origin. If I go over one up two, then the equation is y = 2x^2. over 1 up 3 it is y = 3x^2, over 1 down 1, then y = - x^2, over 1 ... WebJan 25, 2024 · The reflection of such a parabola over the x-axis is simply written as y = -(x^2). In other words, the function of f ( x ) becomes - f ( x ) when reflected over the x -axis. dickson plant nursery
