Question

Please help! Only a couple of questions:

1. What is the solution of log2x + 6 144 = 2?

A: x = −6

B: x = −3

C: x = 3

D: x = 6

2. The function f(x) = 16(5)x represents the growth of a bee population every year in a remote swamp. Jennifer wants to manipulate the formula to an equivalent form that calculates two times a year, not just once a year. Which function is correct for Jennifer's purpose, and what is the new growth rate?

f(x) = 16(5)x; growth rate 500%

f(x) = 16(5)2x, growth rate 8%

f(x) = 16(2.24)x; growth rate 8%

f(x) = 16(2.24)2x; growth rate 224%
