How to evaluate x=0 and dx=.03? I got(1/9)e^(x/9)dx as dy of e^(x/9)and I don't know how I should plug them in.

eh? Just plug them in.
dy = (1/9) e^(x/9) dx
at x=0, dx=.03, we have
dy = (1/9)(1)(.03) = 1/300 
What his means is that if you draw the graph of y=e^(x/9) and then draw the tangent line at x=0, if you move along that line horizontally to the left by .03 (dx), you will move vertically down by 1/300 (dy).
