Exponential Graphs and Key Features

Describe the function's end behavior.

• The graph is increasing toward infinity on the left end and increasing toward infinity on the right side.

• The graph is decreasing toward - infinity on the left end and increasing toward infinity on the right side.
  

• The graph is increasing toward infinity on the left end and decreasing toward -infinity on the right side.

The value of some cell phones changes exponentially after initial release. Here are graphs showing the depreciation of two phones 1, 2, and 3 years after they were released.

What does the point (2, 360) of Phone A represent in this situation?

• Phone A is worth $2 after 360 years

• Phone A is worth $360 after 2 years

• Phone A has an initial amount of $360

• Phone A will be completely depreciated in value after 2 years.

The value of some cell phones changes exponentially after initial release. Here are graphs showing the depreciation of two phones 1, 2, and 3 years after they were released.

The value of some cell phones changes exponentially after initial release. Here are graphs showing the depreciation of two phones 1, 2, and 3 years after they were released.

Which phone is more expensive to buy when it is first released? How do you know?

• Phone A because its initial cost is $1,000

• Phone B because its initial cost is $840

• They both cost the same in the beginning, $0

• Not enough information on the graph to know.
