Front

A relation where an input can have multiple outputs.

Back

What is not a function?

A method to determine if a curve is a graph of a function or not. If a vertical line intersects the curve at more than one point, it is not a function.

Back

What is the Vertical Line Test?

Front

The set of all possible input values (x-values) for which the function is defined.

Back

What is the domain of a function?

Front

The set of all possible output values (y-values) that a function can produce.

Back

What is the range of a function?

Front

The point where a graph intersects the y-axis.

Back

What is the y-intercept?

Front

A function where the graph is a straight line.

Back

What is a linear function?
