well I still dont really know how to do this problem. The first thing i did was I found the derivative of the function which I believe is (e)^x, but what I'm I suppose to do after that.

1. Determine the slope of the tangent line by using the derivative.

2. Use the point-slope form of a line to determine an equation for the tangent line. The form I am talking about is $\displaystyle y-y_0 = m(x-x_0)$. You should have values for $\displaystyle y_0$ and $\displaystyle m$.

3. Find the x-intercept of the line. In other words, set $\displaystyle y=0$ and solve for $\displaystyle x$.
