How to stretch vertically functions
WebFor a function g(x) = f(x) + k, the function f(x) is shifted vertically k units. Vertical shift by k = 1 of the cube root function f(x) = 3√x. To help you visualize the concept of a vertical shift, consider that y = f(x). Therefore, f(x) + k is equivalent to y + k. WebNov 23, 2024 · When we compress a function, we make it smaller in a way. So, vertical compression means we make the function smaller vertically. Our general logarithmic function is of this form: The a...

WebSo, while a = 2 stretches the graph of a function in the case of vertical stretching, it actually compresses the graph of a function in the case of horizontal stretching. We saw this phenomenon before when we studied generalized sine and cosine functions: the period of sin(2x) is half of the period of sinx. We now see that, WebMar 24, 2024 · Solution. Given that B (x) = 2 ∙ A (x), we vertically stretch the graph of A (x) by a range factor of 2. To do this, we can note some points from the graph and discover their equivalent values for B (x). To find the newly bought pairs, let’s multiply each y-coordinate by 2. We can connect these points to develop B (x).
WebTo shift such a graph vertically, one needs only to change the function to f (x) = sin (x) + c , where c is some constant. Thus the y-coordinate of the graph, which was previously sin (x) , is now sin (x) + 2 . All values of y shift by two. PHASE SHIFT WebStretch it by 2 in the y-direction: h (x) = 2/x Compress it by 3 in the x-direction: h (x) = 1/ (3x) Flip it upside down: h (x) = −1/x Example: the function v (x) = x 3 − 4x Here are some things we can do: Move 2 spaces up: w (x) = x3 − 4x + 2 Move 3 spaces down: w (x) = x3 − 4x − 3 Move 4 spaces right: w (x) = (x−4)3 − 4 (x−4)
Webx = +/- sqrt (y/2) Now that we have our function, to move it right 1 we just add 1 to the right side, but then we have to make this equation in terms of y again: x = +/- sqrt (y/2) + 1. (x - 1)^2 = y/2. y = 2 (x - 1)^2. As you can see, trying to shift the function to the right by 1 means that in the y= form, we do the opposite and subtract from ... WebTo stretch a graph vertically, place a coefficient in front of the function. This coefficient is the amplitude of the function. For example, the amplitude of y = f (x) = sin (x) is one. The …
WebI'm not entirely sure what the difference would look like graphically, however, on a table, Khan noticed that the y-values were -1/3 of f (x), so he wrote -1/3f (x). If you selected two x …
