Please help! How exactly would I work out this problem? Use the cut point method to find the solution set of the inequality x^3+3x^2-4x-12>0. One cut point is?

OpenStudy (anonymous):

a. -2 b. 12 c. 1 d. -4

OpenStudy (anonymous):

Would the answer be a.?

OpenStudy (anonymous):

I think so, if the cut points are those values of x that cause the LHS to be zero.

Hmm, sounds right. Thank you for your input.
