Introduction of Exponential Functions

If y = ab^x represents an exponential decay function, what are the possible values of b?

• b = 1

• b > 1

• b < 0

• 0 < b < 1

Is the Graph Linear, Exponential Growth, or Exponential Decay, Neither:

• Linear

• Exponential Growth

• Exponential Decay

• Neither

Is the Graph Linear, Exponential Growth, or Exponential Decay, Neither:

• Linear

• Exponential Growth

• Exponential Decay

• Neither

• Growth because 34 is greater than 1

• Growth because 0.05 is between 0 and 1

• Decay because 34 is greater than 1

• Decay because 0.05 is between 0 and 1

Does the following equation represent an exponential growth or decay function?

• Growth because 3 is greater than 1

• Growth because 5.10 is greater than 1

• Decay because 3 is greater than 1

• Decay because 5.10 is not between 0 and 1

Determine if the table represents linear or Exponential Function.

• growth, 1

• growth, 3

Determine if the graph represents growth or decay. Also determine the value of a for its equation.

• decay, 5

• decay, 1

• growth, 5

• growth, 1

Evaluate when x = 2

f(x) = 2(3)^x

• 9

• 12

• 18

• 36

Which of the following statements best describes the table?

• This is a linear function because the rate of change is constantly adding by 2.

• This is an exponential function because the rate of change is constantly multiplying by 2.

• This is a linear function because the rate of change is constantly adding by 8.

• This is an exponential function because the rate of change is constantly multiplying by 8.
