@Calculus Does the equation x^7 - 8 have a solution on the real line? Why?

OpenStudy (stapeleliz):

What results have you been given to use? The Intermediate Value Theorem? Some rule about odd-degree polynomials?

OpenStudy (anonymous):

None. This is a question from my Calculus paper and I can't seem to relate this to any of the topics taught so far.

OpenStudy (amistre64):

what do you mean by "a solution on the real line?"

OpenStudy (stapeleliz):

If you haven't yet reviewed the Intermediate Value Theorem (something that they covered back in algebra), then maybe you're just supposed to draw the picture...?
