WebThere two transformations going on, the horizontal stretch and the phase shift. To stretch a function horizontally by factor of n the transformation is just f (x/n). So let f (x) = cos (x) => f (x/ (1/2)) = cos (x / (1/2) ) = cos (2x) So the horizontal stretch is by factor of 1/2. 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)

WebDec 16, 2024 · Vertical Stretches and Compressions. When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically … WebDec 20, 2024 · For example, if we begin by graphing a toolkit function, f(x) = 2x, we can then graph two vertical shifts alongside it, using d = 3 : the upward shift, g(x) = 2x + 3 and the downward shift, h(x) = 2x − 3 . Both vertical shifts are shown in Figure 4.2.5. Figure 4.2.5 Observe the results of shifting f(x) = 2x vertically: arti kata cemar
