Homework Help: General Exponential Function

  1. Apr 25, 2012 #1
    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 = abc(x+d)+e

    or

    y = abcx+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.
