Sir. For all the cubic equations. Will one of the x coordinate be 0?. I have my gcse exam day after tomrrow. Will appreciate it if u wuld reply fast

A cubic function has either one or three real roots (which may not be distinct); all odd-degree polynomials have at least one real root. The graph of a cubic function always has a single inflection point. It may have two critical points, a local minimum and a local maximum. It's not necessary for one of the roots to be zero.
