8. Amplitude general information  In standard form, the a represents the amplitude. Amplitude is the distance from the midpoint to the highest or lowest point on the graph. Steps to graph an amplitude change: 1. Graph the parent function. 2. Multiply each y coordinate by the amplitude. 3. Plot each new point with the original x value and new y value.
