Graph factored polynomial from roots
WebApr 8, 2016 · 3 Answers. If the graph of a polynomial crosses the x -axis at r then r is a root and x − r is a factor. If the graph is tangent to the x -axis at r then both the polynomial and its derivative have a root at r, and that means ( x − r) 2 is a factor of the polynomial. That's why we call it a double root. You can carry this geometric analysis ... WebUsing Factoring to Find Zeros of Polynomial Functions. Recall that if f f is a polynomial function, the values of x x for which f (x) = 0 f (x) = 0 are called zeros of f. f. If the equation of the polynomial function can be factored, we can …
