zero

of the rational function p(x)/q(x). These roots are the values of x that make the numerator, p(x), equal to zero. In other words, they are the solutions to the equation p(x) = 0.

If the function of the variable x, is f(x) then the roots are all the values of x (in the relevant domain) for which f(x) = 0.

The Input or X values are called the Domain.

-4,3 are the roots of this equation, so for the values for which the sum of roots is 1 & product is -12

They are called the solutions or roots of the equations.

The allowable values of x are called the "domain", and the resultant set of possible y values are called the "range".

The roots of an equation of the form y = f(x), are those values of x for which y = 0. If plotted on the coordinate plane, these are the points where the graph of y against x crosses (or touches) the x axis.

Yes.

In analytical geometry, the roots of a parabola are the x-values (if any) for which y = 0.

The graph of a polynomial in X crosses the X-axis at x-intercepts known as the roots of the polynomial, the values of x that solve the equation.(polynomial in X) = 0 or otherwise y=0
