Okay my boyfriend and I worked on these two problems last night and couldn't figure it out.

Problem 1:

Solve for :

which I got: .8348214

and Dj said it was undefined.

which both were wrong.

Problem 2:

The rat population in a major metropolitan city is given by the formula where is measured in years since 1994 and is measured in millions.

What was the actual rat population in 1994 ? (not "in millions") What is the rat population going to be in the year 2006 ?

This problem went over both our heads. So please help.
