You have to take the derivative of the curve in order to find the slope of the tangent at x=0.

You differentiate y=e[e/(x+1)], find the gradient of the tangent first.
Then you find a point that lies on the curve with the original equation, and use that to find c in y=mx+c, which should equal y=x+1 according to you.
