The graph below represents a rock climber’s height as she ascends a hill.

The graph is.....

• Linear

• Nonlinear

The graph below represents a rock climber’s height as she ascends a hill.

Is the graph a function? Explain.

The graph below represents a rock climber’s height as she ascends a hill.

What is the y-intercept and what does it represent?

• (70 , 50) ; it represents the time in seconds it takes for the climber to get 50 feet up

• (70 , 50) ; it represents that height the climber is at after 45 seconds.

• (0 , 10) ; it represents the time in seconds it takes the climber to get 10 feet up

• (0 , 10) ; it represents the height the climber is at at the beginning of his climb/start point

The graph below represents a rock climber’s height as she ascends a hill.

Why would there not be an x-intercept for this situation?

Consider the following graph of a quadratic function. Define the range

• Trick Question!

Consider the following graph of a quadratic function.

Circle the section of the graph that is increasing. If not possible write "N/A" on the graph.

Consider the following graph of a quadratic function. Circle the section of the graph that is decreasing. If not possible write "N/A" on the graph.
