Which of the following exponential functions goes through the points (1, 6) and (2, 12)?



f(x) = 3(2)x

f(x) = 2(3)x

f(x) = 3(2)−x

f(x) = 2(3)−x

Answer 1

Can someone plz help me

Answer 2

What do you think? :D

Answer 3

The last one

Answer 4

But not really sure

Answer 5

ya, it is :D

Answer 6

are u sure why?

Answer 7

definitely not D

Answer 8

Then B?

Answer 9

lets try \[f(x) = 3(2)^x\]

Answer 10

and then we can try \[f(x)=2(3)^x\] and see which one works, instead of guessing A, B, ...

Answer 11

both give you \[f(1)=6\] the question is, which one gives \(f(2)=12\)

Answer 12

A would be \[f(2)=3\times 2^2\] and B would be \[f(2)=2\times 3^2\] which one equals 12?

Answer 13

A

Answer 14

So the answer is A?
