So for the equation to be true y needs to be … WebGiven a function f (x), f ( x), a new function g(x) = af (x), g ( x) = a f ( x), where a a is a constant, is a vertical stretch or vertical compression of the function f (x) f ( x). If a > 1 a > 1, then the graph will be stretched. If 0 < a < 1 0 < a < 1, then the graph will be compressed.

How do you figure out if a parabola is stretched or shrunk?

The general formula is: y=ax^2 y = ax2 ! Remember If a ∣a∣ > 1, the graph is steeper than the standard parabola and is stretched. If a ∣a∣ < 1, the graph is flatter than the standard parabola and is compressed. Example \color {green} {g (x)=\frac12x^2} g(x)= 21x2 descargar router wifi para pc

WebTo stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ). … WebSep 8, 2024 · You can shift a parabola based on its equation. [11] 1 Shift a parabola upward. Consider the equation y = x2 +1. This shifts the original parabola upward 1 unit. The vertex is now (0, 1) instead of (0, 0). It will retain the exact shape of the original parabola, but every y-coordinate will be shifted upward 1 unit. WebThe standard parabola can be stretched and compressed with the parameter a a.

"WebIf you have the parabola written out as an equation in the form y = 1/ (2 [b-k]) (x-a)^2 + .5 (b+k) then (a,b) is the focus and y = k is the directrix. This is for parabolas that open up or down, or vertical parabolas. For those that open left or right it is diffeent. " - How to stretch a parabola

Webwhere: a = vertical stretch or shrink of the parabola and (h, k) are the (x, y) coordinates of the vertex of the parabola. ... The Parabola always produces a "U"-shaped graph which can open upwards or downwards depending on the value of "a". Given the values of a, h, and k, fill them into the formula to produce the equation of the graph ... So you may see a form such as y=a(bx-c)^2 + d. The parabola is translated (c,d) units, b reflects across y, but this just reflects it across the axis of symmetry, so it would look the same. A negative a reflects it, and if 0
