Is the table linear or exponential?

• Linear because the rate of change is constant

• Exponential because the rate of change is NOT constant

Is the table linear or exponential?

• Linear because the rate of change is constant

• Exponential because the rate of change is NOT constant

Consider the equation y=200(1.08)^x which models the increase in value of an autographed Annie program. Let y = the value of the item, let x = the number of years since the performance. What does the 1.08 in the equation indicate?

• The value of the item is increasing by $1.08 each year.

• The value of the item is increasing by 1.08% each year.

• The value of the item will increase to $200 1.08 years after purchase.

• The value of the item is increasing by 8% each year.

Given the function:  $y\ =\ 23\left(1.36\right)^x$  ; does the function represent exponential growth or decay and why?

• Growth because 1.36 is larger than 1

• Growth because 23 is larger than 1

• Decay because 1.36 is larger than 1

• Decay because 23 is larger than 1

Given the function:  $y\ =\ 10\left(0.25\right)^x$  ; does the function represent exponential growth or decay and why?

• Decay because 0.25 is between 0 and 1

• Decay because 0.25 is larger than 1

• Growth because 10 is larger than 1

• Growth because 0.25 is between 0 and 1
