A ball bounces several times after it is dropped. The graph shows the height of the ball over time.

Height is measured in meters and time is measured in seconds.

Select the statement that is true about the graph and the situation it represents.

• The horizontal intercepts show the times when the ball hits the ground.

• The ball hits the ground at 2 seconds.

• The function reaches its minimum value at 1.9 seconds.

• Based on the trend of the graph, after 3 seconds, the ball will be 3 meters high.

A ball bounces several times after it is dropped. The graph shows the height of the ball over time.

Height is measured in meters and time is measured in seconds.

Select ALL the statements that are true about the graph and the situation it represents.

• The vertical intercept of the graph shows the height from which the ball was dropped.

• The function has a minimum value of 0.

Function M gives the number of miles driven by a delivery driver after d days.

What does the expression M(5) represent in this situation?

• The mileage driven after 5 days

• The driver drives 5 miles in one day

• The delivery driver drives 5 miles in 5 days

• The driver drives 5 miles per day

Function M gives the number of miles driven by a delivery driver after d days.

What does the equation M(15) = 3000 represent in this situation?

• The driver is able to drive 15 miles per day

• The driver is able to drive 3000 miles

• The driver drives a total of 3000 miles in 15 days

• The driver drives a total of 15 miles in 3000 days

Function M gives the number of miles driven by a delivery driver after d days.

Use function notation to represent the statement.

After driving for 10 days, the driver had driven 2400 miles.

• M(x) = 10

• M(x) = 2400

• M(10) = 2400

• M(2400) = 10

Function M gives the number of miles driven by a delivery driver after d days.

Use function notation to represent the statement.

The driver had driven 450 miles after 2 days.

• M(2) = 450

• M(450) = 2

• M(x) = 2x + 450

• M(x) = 450x + 2

Functions and give the population of City A and City B, respectively,  years since 1990. In each function, population is measured in millions.

Which statement is true?

• A(10) = B(10)

• A(10) < B(10)

• A(10) > B(10)

• A(10) - B(10) = 2 million
