The question is : Show that one of the root of the equation y^3 - 3y + 4 = 0 lies between -3 and -2.(adsbygoogle = window.adsbygoogle || []).push({});

REMEMBER : If you want to use some statement, Law, identity or logic, please PROVE it first before you proceed to answer the question..

Difficulty for me is, normally we are asked to solve for the exact value of the roots when given an equation, but now we are asked to find the range for one of the roots, hence i feel so weird and have no idea how to continute.

Any expert, if you know, please teach me, i appreciate u help, thanks you.
