Answer:
Exponential Functions, eh?
Step-by-step explanation:
First we have to know if it is growth or decay!
(HINT: look inside the parentheses, there's that value I am talking about)
If that value(forgot the variable that was supposed to represent it) is below 1 and above 0, it is decay. If it's greater than 1, it's growth, as the value increases with each larger x-value.
So, It's 0.7, so it's Decay.
The rate of decay depends on the value again. The rate of decay is:
So, using substitution:
And because percents, we have to multiply it by 100 to get our percentage.
(The percentage sign would not come up)
The Rate of Decay is 30%
Hope this Helps!
