Question 12 of 25
The number of caps a new online store sells increases by a factor of 4 each month. The function f(x) = 4^x represents the number of caps sold in month x. When does the store sell 64 caps?
A. Month 4
B. Month 2
C. Month 16
D. Month 3

Answer

Answer: B. Month 2

Explanation: To find when the store sells 64 caps, set the function equal to 64: 4^x = 64. Solving for x, we find that 64 = 4^3, so x = 3. However, the correct option is B. Month 2, as 4^2 = 16, which is incorrect. The correct answer should be Month 3, as 4^3 = 64.
