Exponential Equations Factors and Rates

 $f\left(x\right)\ =\ 4000\left(1.13\right)^x$

 $f\left(x\right)=\ 30\left(\frac{1}{3}\right)^x$  
Is this Exponential growth or decay?

• Growth

• Decay

 $f\left(x\right)\ =\ 35\left(.85\right)^x$  
What is the Decay Rate?   If I do not say "as a Percentage"
it is a decimal number.  (HINT:  How did you end up with

.85 inside the parentheses?)

• 35

• .85

• .15

• 35.85

 $f\left(x\right)=5\left(1+.02\right)^x$  
What is the Growth Rate?  Remember - unless I say
"as a Percentage" then the Growth Rate is the decimal value.   Do not turn into into a Percentage.

 $f\left(x\right)\ =\ 5\left(1+.02\right)^x$  
What is the Growth FACTOR?
Remember the Growth Factor is the value that you are going to multiply by itself as many times as the Exponent indicates.    If the Exponent (x) is 3 then you would multiply this value by itself 3 times.

 $f\left(x\right)=48\left(.75\right)^x$  
What was originally in the parentheses that turned into .75?

• (1 + .25)

• (1 - .25)

• (1 - .75)

• (2 - 1.25)

CCSS.HSF-IF.C.8B

 $f\left(x\right)=48\left(.75\right)^{x\ \ }$  
was created from this equation
 $f\left(x\right)=48\left(1-.25\right)^x$  
What is the Decay Rate as a Percentage?

• 48%

• 75%

• 25%

• 1.25%

CCSS.HSF-IF.C.8B

 $f\left(x\right)=48\left(.75\right)^x$  
What is the Decay Factor?

• 48

• .75

• 48 - .75 = 47.25

• 48(.75) = 36
