A complicated polynomial graph ;y=3e^x-2

I am studying for a pre-calc. final. I am stuck on the question y=3e^x-2. I have gotten the answer through desmos but am struggling to solve the problem on my own. Any help appreciated, thank you.

In principle, no need for logarithm. But if you'd like to use logarithm, then you can do following:
y=3ex-2. So (y+2)/3=ex, then log(y+2)-log(3)=x. Does it help?
Once you take log, you will have a different function. logy instead of y.
