Unit 4 Mid Unit Assessment - original

Front

What is the average rate of change?

Back

The average rate of change is the change in the value of a function divided by the change in the input value over a specific interval.

Front

Calculate the average rate of change from 20 to 40 minutes if the output changes by -40 gallons.

Back

-2 gallons per minute.

Front

What does d(8)=300 mean in the context of a function d(x) where x is gallons of gas?

Back

A car with 8 gallons of gas can travel 300 miles.

Front

What does h(4)=5 represent in the context of a function h(t) for plant height?

Back

After 4 weeks, the plant is 5 inches tall.

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols, typically in the form f(x), where f is the function and x is the input.

Front

If f(1990) = 214, what does this indicate?

Back

The function f outputs 214 when the input is 1990.

Front

How do you calculate the average rate of change for a climber's altitude?

Back

Average rate of change = (Change in altitude) / (Change in time).

Front

What is the average rate of change if a climber goes from 400 feet to 700 feet in 4 hours?

Back

75 feet per hour.

Front

What is the significance of the notation h(t)?

Back

h(t) represents the height of a plant at time t.

Front

What does it mean if a function is increasing?

Back

A function is increasing if the output values rise as the input values increase.
