What is a vertical translation in the context of function transformations?

Back

A vertical translation shifts the graph up or down without changing its shape.

Front

How does a horizontal dilation affect the graph of a trigonometric function?

Back

A horizontal dilation stretches or compresses the graph along the x-axis.

What is the general form of a sine function?

Back

f(t) = A sin(B(t - C)) + D, where A is amplitude, B affects period, C is horizontal shift, and D is vertical shift.
