Linear or Exponential?

• Linear

• Exponential

Linear or Exponential?

• Linear

• Exponential

• The linear function grows faster than the exponential function.

• The exponential function grows faster than the linear function.

• Both functions grow at the same rate.

• The growth rates cannot be compared.

Why is this function linear?

• This is a linear function because it does not have a constant rate of change

• This is a linear function because it creates a curved line.

• This is a linear function because it have a constant rate of change.

• This is a linear function because it's y-intercept is (0,2)

The rate of change of two functions are being compared. One function, f(x) is represented by the equation f(x) = 5x + 9, 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.
