What is a phase shift in periodic functions?

Back

A phase shift is a horizontal shift of the graph of a function. It occurs when the input variable is adjusted by a constant.

How can you identify a periodic function from its graph?

Back

A graph is periodic if it shows a repeating pattern over a specific interval.
