Interpreting Graphs of Functions

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line. It has a constant rate of change.

Front

What is a nonlinear function?

Back

A nonlinear function is a function that does not graph to a straight line. Its rate of change varies.

Front

What does it mean for a function to have a relative maximum?

Back

A relative maximum is the highest point in a specific interval of the graph.

Front

What does it mean for a function to have a relative minimum?

Back

A relative minimum is the lowest point in a specific interval of the graph.

Front

What is the difference between stationary and moving in a graph?

Back

Stationary means the object is not moving, while moving indicates a change in position over time.

Front

How can you tell if a graph is increasing or decreasing?

Back

A graph is increasing if it goes up from left to right and decreasing if it goes down from left to right.

Front

What does it mean when a graph is flat?

Back

A flat graph indicates that the function is constant; there is no change in value.

Front

What is the significance of points on a graph?

Back

Points on a graph represent specific values of the function at given inputs.

Front

What does it mean for a function to be continuous?

Back

A continuous function has no breaks, jumps, or holes in its graph.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a graph where the value of y is zero.
