1A Exponential Decay and Growth

What is the Exponential equation?

• $y=mx+b$

• $y=a\left(b\right)^x$

• $y=b\left(a\right)^x$

• $y=abx$

In the exponential function, what does a represent?

• growth factor

• decay factor

• initial value

• exponent

In the exponential function, what does b represent?

• growth/decay factor

• initial value

• number of times something occurs

• function

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?

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
