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.
