Question 622201
<font face="Times New Roman" size="+2">


The *[tex \LARGE x]-intercept is the point where the graph crosses the *[tex \LARGE x]-axis, which is to say the point in the solution set that has the *[tex \LARGE y]-coordinate equal to zero.  The ordered pair looks like *[tex \LARGE (a,0)].  The only thing you need to do is figure out the value of *[tex \LARGE a].  To do that, substitute 0 for *[tex \LARGE y] in the equation and do the required arithmetic to determine the value of *[tex \LARGE x] that results.  That will be your *[tex \LARGE a] value.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
