WebIn general, the parabola \(y=ax^2\) is obtained from the basic parabola \(y=x^2\) by stretching it in the \(y\)-direction, away from the \(x\)-axis, by a factor of \(a\). Exercise 2 Sketch the graphs of \(y=\dfrac{1}{2}x^2\) and \(y=x^2\) on the same diagram and describe the relationship between them. 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.

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. 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. fishing in wow guide

WebThe standard parabola can be stretched and compressed with the parameter a a. 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.
