Circle appropriate response, N for no answer. If you know three linear factors of a cubic polynomial, you can determine all the zeros of the function. All polynomial functions are continuous on the interval .
Every quadratic function has either a local maximum or local minimum.
The graph of a second degree polynomial may cross the x -axis 3 times. T F N Given any third degree polynomial function, you can always find an interval where it is increasing. Given any fourth degree polynomial function, you can always find an interval where it is increasing. A fourth degree polynomial function will have at most four zeros. If the discriminant of a quadratic function is negative, then the function has no real zeros.
