Answer

Brief Explanations:

To find where a quadratic function (f(x)) is negative efficiently, we need to quickly identify its roots (x-intercepts) and the direction it opens. The factored (intercept) form directly gives the roots, and the leading coefficient tells us if the parabola opens up or down, which lets us immediately determine the intervals where the function is negative.

Answer:

The factored (intercept) form: (f(x) = a(x - r_1)(x - r_2)) where (a \neq 0), and (r_1, r_2) are the roots of the function.
