Rate of Change Linear

Look at the table. Which of the following best represents the situation in the table?

• If you rent a scooter for 8 hours you will pay $52.00.

• If two people each rented a scooter for 3.5 hours

  per day for 4 days, they would pay $164.00.

• If two people each rented a scooter for 1 hour each

  day for 2 days, they would pay $21.00.

• Not here.

The rate of change of two functions are being compared. One function, f(x) is represented by the equation f(x) = -5x – 1, while the other function, g(x) is represented in the table. Which is true?

• The rate of change for f(x) is less than the rate of change for g(x).

• The rate of change for g(x) is less than the rate of change for f(x).

• The rate of change for f(x) and g(x) are equal.

• The rates of change cannot be compared because f(x) is a linear function and g(x) is an exponential function.

The rate of change of two functions are being compared. One function, f(x) is represented by the equation f(x) = 3x + 2, while the other function, g(x) is represented in the table. Which is true?

• The rate of change for f(x) is less than the rate of change for g(x).

• The rate of change for g(x) is less than the rate of change for f(x).

• The rate of change for f(x) and g(x) are equal.

• The rates of change cannot be compared because f(x) is a linear function and g(x) is an exponential function.
