Linear function of x

  1. Oct 27, 2008 #1
    Hey guys, I'm absolutely stuck on how to do this. I really don't even know where to begin. A push in the right direction would be great! Here's the problem:

    Let y=(6.3)(1.5)x. Write ln(y) as a linear function of x.

    I came up with this, bu I don't think it's right:

    ln(y)= x ln(1.5) + ln(6.3)

    Is that what they're looking for? Or am I way off?

    Yes, that looks good. You can see that ln(y) is a linear function of x, because x appears only raised to the first power.

    Great, thanks for the confirmation!
