Interpreting Graphs of Functions

Front

What is happening in this graph from point A to B? HINT: Look at the axis labels.

Back

The object is moving at a constant speed.

Front

In the ordered pair (4,9), which number is the y-coordinate?

Back

Front

What is happening at point D?

Back

Front

Describe the bus’s motion from A-B.

Back

Back

(X,Y)

Front

What does the x-axis represent in a graph?

Back

The x-axis typically represents the independent variable.

Front

What does the y-axis represent in a graph?

Back

The y-axis typically represents the dependent variable.

Front

What does it mean if a graph is increasing?

Back

The values of the dependent variable are getting larger as the independent variable increases.

Front

What does it mean if a graph is decreasing?

Back

The values of the dependent variable are getting smaller as the independent variable increases.

Front

What is a function?

Back

A relation where each input has exactly one output.
