Consider the function y is equal to A sine b x , where A is greater than 0 and b is greater than 0 Which change compresses the graph vertically?

The amplitude A determines the graph’s vertical size: its maximum and minimum values are A and −A. Decreasing A brings both values closer to zero, compressing the graph vertically. Changing b affects the graph horizontally, not vertically.
