What is the Correct General Expression for an Exponential Function?

[Peter G.]

Hi,

I am working on a modeling exercise and I would like to know which is the correct general expression for a Exponential Function:

y = ab^c(x+d)+e

or

y = ab^cx+d+e

Thanks in advance,
Peter G.

Either would be fine, IMO, although the first makes horizontal shifts more obvious.

Hi,

Thanks a lot for your response! I also prefer the first one because it reminds me of how the Sine Function is set up, making, as you said, the horizontal shift more obvious for me.
