Exploring Functions: Vertical Line Test and Domain/Range

What is a function in terms of X and Y values?

• A relationship where each Y value corresponds to multiple X values.

• A relationship where each Y value corresponds to exactly one X value.

• A relationship where each X value corresponds to exactly one Y value.

• A relationship where each X value corresponds to multiple Y values.
