Applying and analysing exponential and logarithmic functions

Use the following function rule to find f(8).
f(x) = (3)^x  + 4
f(8) = ____

• 1.73
• 28
• 6565
• 6666

• Linear Growth

• Linear Decay

• Exponential Growth

• Exponential Decay

• None of these

 $f\left(x\right)\ =\ e^{.031}$  Select the correct description for the function.

• The function represents growth because e >1

• The function represents decay because e > 1

• The function represents growth because .031  > 0

• The function represents decay because .031  > 0

 Atmospheric pressure  (in atmospheres) can be modeled by P=(0.99988)^a, where a is the altitude (in meters).Identify the initial amount, decay factor, and decay rate (%).   

Initial amount  ______________

f(x) = 3^{x
Find f(-4)}

• -81
• 81
• 1/81
• -1/81

• the common ratio

• the growth factor

• the x-intercept

• the base of the exponent

This is an example of: $f\left(x\right)=\ 25\ \left(\ 0.20\right)^x$  

• Linear Growth
