what even is this,

A cubic equation has degree 3. That means that the highest exponent of x (or whatever variable is being used) is 3. This means the function can have 0, 1, 2 or 3 roots.

Whatever the highest exponent of the variable is tells us the highest number of roots it can have. It can have that many or fewer but no less than 0.

The possible numbers of real roots for a cubic function are 1 and 3. This is because they can be the roots of cubic function because most of the odd numbers are roots for cubic function.
