Question 637219
<font face="Times New Roman" size="+2">


a) *[tex \LARGE C(x)\ =\ R(x)], so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.1x^2\ +8x\ +\ 400\ =\ ???]


Can't finish because of your typo in the defintion of R(x).  Put in the correct definition of R(x), then solve for *[tex \LARGE x_e]


b) Evaluate *[tex \LARGE C(x_e)] and *[tex \LARGE R(x_e)]

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