The graph of h has transformed f in two ways: f(x + 1) is a change on the inside of the function, giving a horizontal shift left by 1, and the subtraction by 3 in f(x + 1) − 3 is a change to the outside of the function, giving a vertical shift down by 3. The transformation of the graph is illustrated in Figure 3.6.9.
The Period goes from one peak to the next (or from any point to the next matching point): The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position.
The horizontal shift is C. In mathematics, a horizontal shift may also be referred to as a phase shift.* (see page end) The easiest way to determine horizontal shift is to determine by how many units the "starting point" (0,0) of a standard sine curve, y = sin(x), has moved to the right or left.
Oct 25, 2016 · therefore starting with the point $(X,Y)$ on the parent function, the chain of transformation is this: $(X,Y)\rightarrow (\frac{X}{k}+b,a\cdot Y+c)$ I do the horizontal transformations first:
Jan 30, 2024 · Remember twice the size of 0 is still 0, so the point (0,2) remains at (0,2) while the point (2,0) will stretch to (4,0). Next, we horizontally shift left by 2 units, as indicated by the \(x+2\). Last, we vertically shift down by 3 to complete our sketch, as indicated by the -3 on the outside of the function.
This example combines a vertical shift with a horizontal shift. a) Graph the function f (x) = (x - 2) 2 - 3. b) What is the parent function associated with this transformation? c) Describe the movement of this function from the parent function. d) State the coordinates of the minimum points of the parent function and of f (x).

We just saw that the vertical shift is a change to the output, or outside, of the function. We will now look at how changes to input, on the inside of the function, change its graph and meaning. A shift to the input results in a movement of the graph of the function left or right in what is known as a horizontal shift, shown in Figure 5.
