We will see that the exponential decay function is:
f(x) = 175*(0.8)^x
The general exponential decay is:
f(x) = A*(1- r)^x
Where:
Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.
20%/100% = 0.2
Replacing that in the exponential function, we get:
f(x) = 175*(1 - 0.2)^x
f(x) = 175*(0.8)^x
