Exponential Growth and Decay

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?

What is the initial value to the function

 $y=2^x$
