20. Suppose a population of 175 crayfish doubles in size every month. The function f(x)=175(2^x) gives the population after x months. How many crayfish will there be after 1 year?
A) 2,100
B) 4,200
C) 716,800
D) 61,250
I think the answer is D. Am I correct?
To find the number of crayfish after 1 year, we need to substitute x with 12 in the function f(x)=175(2^x).
f(12) = 175(2^12)
= 175(2^12)
= 175(4096)
= 716,800
Therefore, the correct answer is C) 716,800.
To find the population of crayfish after 1 year, we need to substitute x = 12 into the function f(x) = 175(2^x).
f(12) = 175(2^12)
f(12) = 175(2^12)
f(12) = 175(4096)
f(12) ≈ 716,800
Therefore, the correct answer is C) 716,800.
