Answer:
Exponential growth
The growth rate is 82%
=========================================
Step-by-step explanation:
Anything of the form y = a*b^x will have the value of b directly determine the growth or decay rate. The value a = 45 is ignored.
Set b = 1.82 equal to 1+r and solve for the variable r.
1+r = 1.82
r = 1.82-1
r = 0.82
The growth rate is 82%
If r was negative, then we'd have exponential decay instead.
