By looking at the graph, I know it crosses the x axis; however, I don't remember or know how to do this problem.

Hint: If f(x) = e^{x} + x - 2, look at f(0), f(1) and f '(x).

I know what f(0) and f(1) are and f '(x) = e[tex]^{x}[/tex] + 1

How is that suppose to help?

You mean "supposeI know what f(0) and f(1) are and f '(x) = e[tex]^{x}[/tex] + 1

How is that suppose to help?

What does the fact that f(0) and f(1) have opposite signs tell you? What does having a positive derivative tell you? And, of course, I'm just assuming I know what your actual question was since your original post doesn't actually contain a question.

No extra charge for the English.

How are we supposed to know what the question was if you don't tell us? So, what was the question? And did the hints I gave you help you solve it?
