Graphs are a way to turn words into pictures.

Be sure to read the graphs from LEFT to RIGHT.

Increasing

Imagine a car suddenly accelerates, the speed will keep on increasing

Decreasing

Imagine a car slowing down till it comes to a stop

Stays the same

Imagine a car going at a constant speed

Example 1

Divide the graph into sections where the graph changes directions. Then label the sections as:

- increasing

- decreasing or

- same

Example 2

Divide the graph into sections where the graph changes directions. Then label the sections as:

- increasing

- decreasing or

- same

A graph can be continuous or discrete.

Continuous means the situation can include fractions or decimals.

A graph can be continuous or discrete.

Discrete means the situation must have only specific amounts.

TEST YOURSELF!!!

Sketch a graph of each situation. Tell whether the graph is continuous or discrete.

Example 1:

The heart rate of someone walking, then running, then resting.
