Question

PLEASE HELP!!!!!!

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

I think its either C or D

Answer 1

it is either C or D

Answer 2

both give \(12\) if \(x=1\) so try \(x=2\) and see which one gives \(36\)

Answer 3

which one equals 36?
\[f(2)=3\times 4^2\] or \[f(2)=4\times 3^2\]?

Answer 4

Hold on im going to work it out

Answer 5

f(2)=4x9 is the one that gives me 36

Answer 6

yeah
pick D

Answer 7

f(2)=4x3^2 is the one sorry lol

Answer 8

you got it
