**Is there a formula to find x of a third degree polynomial**

What is an example of a 4th degree polynomial with no x-intercepts. I have looked everywhere but can not find one.... A polynomial function is defined for all x, ranging from minus infinity to plus infinity. Since it is defined for all x, it is defined for x = 0 and this is the point where it … intersects the y-axis which is …

**The function p is a fourth-degree polynomial with x**

Using factoring to find zeros of polynomial functions. Recall that if f is a polynomial function, the values of x for which f (x) = 0 are called zeros of f. If the equation of the polynomial function can be factored, we can set each factor equal to zero and solve for the zeros . We can use this method to find x-intercepts because at the x-intercepts we find the input values when the output... This is a fourth-degree polynomial, so it has, at most, four x-intercepts, and I can see all four of them on the graph. This means that I won't have any complex-valued zeroes. This means that I won't have any complex-valued zeroes.

**Graphing Polynomial Functions Problem 2 - Precalculus**

To use finite difference tables to find rules of sequences generated by polynomial functions. In Chapter 4 we looked at second degree polynomials or quadratics. A third degree polynomial is called a cubic and is a function, f, with rule f (x) = ax3 +bx2 +cx +d,a = 0 A fourth degree polynomial is called a quartic and is a function, f, with rule f (x) = ax4 +bx3 +cx2 +dx+e,a = 0 In Chapter 4 it how to go undergound in ark 12/10/2010 · [itex]x^4+ x^3+ x^2+ x+ 1[/itex] is a "cyclotomic" polynomial whose zeros are equally spaced around the unit circle in the complex plane. One way to solve this is to convert it to a 5th degree equation (for which there is no general formula!).

## How To Find X Intercepts Of X 4th Degree Polynomial

The polynomial is to the fourth degree, which means you have a x 4. You know two of the roots are x=sqrt(2)i and x=2, so you know two of the factors right off the bat. You know that the y-intercept is 8, and that when x=-1, the function is equal to zero.

- -show all the maxima, minima, and intercepts -allow to read (x,y) coordinates of all the x and y intercepts and all the maxima and minima on the graph easily and clearly. -have a meaningful title that contains the problem number.

- There is no simple way. A polynomial of the form f(x) = ax4 + bx3 + cx2 + dx + e may have four real factors: it may have none. Binomial factors will be of the form px + q, where p is one of the factors of a and q is one of the factors of e.
