Question

How do I find the inverse of this relation: y=3(2)^x???

Answer 1

\[y=3*2^x\]

Answer 2

this is the question ?

Answer 3

yup!

Answer 4

ok divide both sides by 3

(y/3) = 2^x

now introduce ln in both sides..
does it help?

Answer 5

This is what I've done so far:

y=3(2)^x
x = 3(2)^y
x/3 = 2^y
logx/3 = log2^y
logx/3 = ylog2
log(x/3)/log2 = y

Using change of base formula: log[2](x/3).... but it's not right :(

Answer 6

the correct answer states,

\[y = \sqrt[3]{2\div3}\]

Answer 7

i mean, \[y = \sqrt[3]{2}\div3 \]

Answer 8

it is the right answer .. something wrong with the answer that you say its correct

Answer 9

really?.. oh, okay. thank you!
