Answer:
A) 32
Step-by-step explanation:
I will assume the function is
f(x) = 32 (1.5)^x
This is in the form
y =a b^x
in which a is the initial value, b is the growth rate, x is the time
a =32, which is the initial population
b= 1.5, which means 1.5-1 = .5. which means it grows at a 50% increase
x = number of years
Answer:
