Question

Convert to logarithmic form
-2^x+3

Answer 1

so 3 is exponent too ?

Answer 2

Start by subtracting the 3. -2^x = -3

Answer 3

@qpHalcy0n there is no equation here, though.

Answer 4

Then what can you really do here? There is no problem. Problem solved.

Answer 5

So you cant convert it to a log? I didn't think you could have a log base -2 anyway.

Answer 6

You didn't give enough information for us to do anything.

Answer 7

See, I thought that since this was in exponential form, you could make it a log. I know it says +3, but that means it is moved up three on the graph.

Answer 8

So how would you find the inverse of this problem?

Answer 9

\[\text{So then you meant }y=-2^x+3\text{?}\\
\ \ \ y=-2^x+3\\
\ \ \ y-3=-2^x\\
\ \ \ 2^x=3-y\\
\ \ \ x=log_2[3-y]
\]

Answer 10

Thanks! Sorry, that is what I meant.
