Question

Which of the following options is an equivalent function to f(x) = 3(2)^3x


a. f(x) = 24^x

b. f(x) = 27(8)^x

c. f(x) = 3(8)^x

d. f(x) = 3(8x)

Answer 1

Word to the wise: Please express exponentiation properly:

Correct: f(x) = 3(2)^(3x)

Vague: f(x) = 3(2)^3x

Note: \[a ^{bc}=(a^b)^c\] Can you use this fact to answer the question at hand?
