6.3: Exponential Functions Practice

Match the following

• Decay

• Growth

• 
• y-intercept

• 
• Growth/Decay Factor

• b

• Exponential Function Equation

• a

If b>1, this tells me I have an exponential __________.

If 0<b<1, this tells me I have an exponential ________.

 $y=24\left(0.47\right)^x$  

• growth

• decay

 $y=2.7^x$  

• growth

• decay

In the function

 $y=0.3\left(1.08\right)^x$  , what is my growth factor?

What is the initial value to the function

 $y=2^x$  

35% as a decimal is

• 3.5

• 0.035

• 35.0

• 0.35

Select all that apply to the function

 $y=5\left(0.88\right)^x$  

• this represents an exponential decay

• my initial value is 5

• my decay factor is 0.88

• when graphed, the function will be decreasing 

I the exponential equation

 $y=35000\left(1.12\right)^x$ represents the increase of income in a year , how much income would you have in 9 years?
