Front

What is a linear function?

Back

A function that graphs to a straight line and has a constant rate of change.

Front

What is a nonlinear function?

Back

A function that does not graph to a straight line and has a variable rate of change.

Front

What is the Vertical Line Test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What does the slope of a line represent?

Back
