**Help finding the zeros of a cubic function? Yahoo Answers**

To use the remainder theorem and the factor theorem to solve cubic equations. To find equations for given cubic graphs. To apply cubic and quartic functions to solving problems. 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... The newtons-method procedure takes as its arguments a procedure that computes the function for which we want to find a zero, along with an initial guess. That means the cubic procedure itself needs to return a procedure.

**pre calc math find cubic function when given zeros**

If the equation is pretty easy you can simply find the factors or zeroes of the equation by looking at the constant. for e.g. [math] ax^3 + bx^2 + cx + d = 0[/math] At least, one of the factors of d (both negative and positive ) will be the zero of the equation.... The derivative of a cubic function is a quadratic function, a parabola. The process of finding the derivative of a function is called differentiation. The value of the derivative function for any value x is the slope of the original function at x. To find the derivative at a point we can draw the tangent line to the graph of a cubic function at that point: But how can we draw a tangent

Given: How do you find the turning points of a cubic function? The definition of A turning point that I will use is a point at which the derivative changes sign. According to this definition, turning points are relative maximums or relative minimums. Use the first derivative test: First find the first derivative f'(x) Set the f'(x) = 0 to find the critical values. Then set up intervals that how to know if your steering pump is bad Given: How do you find the turning points of a cubic function?

## How To Find Zeros Of A Cubic Function

Clicking in the checkbox 'Zeros' you can see the zeros of a cubic function. Playing with the red points or translating the graph vertically moving the violet dot you can see how the zeros mix together in a double zero or in a triple zero.

- Class will begin with a discussion of how to find the zeros of a cubic function that does not have three real roots. My notes for the details of this discussion are included as a resource.
- Using Solver to Find the Zeros of a Function. Suppose we have the function y = x 3 -6x 2 +11x-5.9 and we want to find the zeros of this function. It helps if we know this is a cubic function and there are at most three zeros.
- You have the relations $2b = 3a, c = -4b = -6a$ by setting the derivative to zero at those two points. Now, go back to your original equation. The relations allow you to eliminate two of the four unknown constants.
- Question:Given a function and one of its zeros, find all of the zeros of the function. f(x)=x^3-4x^2+6x-4 the given zero is 2 I know the answer.
