Question

Which of the following exponential functions goes through the points (1, 12) and (2, 36)?

Answer 1

The question seems to be incomplete, here is the complete question:

Which of the following exponential functions goes through the points (1, 12) and (2, 36)? f(x) = 4(3)−x f(x) = 3(4)−x f(x) = 3(4)x f(x) = 4(3)x

Answer:

4·3^-2 = 4/9 ≠ 36

3·4^-2 = 3/16 ≠ 36

3·4^2 = 48 ≠ 36

4·3^2 = 36 = 36

So the final answer for this question is: f(x) = 4(3)^x
