Answer:
A) Exponential decay, 55% decrease
Step-by-step explanation:
The <em>b</em><em> </em>is less than 1, so that means it's decaying. Since <em>b</em><em> </em>= 0.45 and that the formula for an exponential decay is <em>a</em>(1- percent in decimal form)^x, all you have to do is find out what the decimal was BEFORE you subtracted it from 1.
So: 1 - x = 0.45
x = 0.55
0.55 = 55%
