Statistical Translation relationships?

Hello there! this question is from an AP Statistics and Data Management student.
I an having trouble understanding the concept of transforming data, in order to find a stronger Correlation of the data to have better predictions.

For example: The Logarithm transformation
When will we use it? Why? How do we go about transforming it into such?

The Power Transformation
The Exponentional Growth Transformation

What signifies that this certain transformation is used?

How do we invert them?

Re: Statistical Translation relationships?

Well, the inverse of a log transform is the exponential transform, and vice versa.

The problem is that one often checks only for linear relationships, as in y = Ax for some A. But maybe this is too limiting. Doing a transform simply checks the possibility that in fact the relationship isn't linear. For example, maybe it's logy = Ax for some A. Or y = Ae^x for some A (the same relationship, actually). Does that make sense?

As for how to guess - that's just a guess.
