How to Find a Polynomial Function That Has Zeros?

Answer There are two types of polynomials, those that have zeros and those that don't. If you think about it graphically, the polynomial must touch the "x" axis to have a zero. If you are finding polynomi... Read More »

How to Write Polynomial Functions When Given Zeros?

The zeros of a polynomial function of x are the values of x that make the function zero. For example, the polynomial x^3 - 4x^2 + 5x - 2 has zeros x = 1 and x = 2. When x = 1 or 2, the polynomial e... Read More »

Determine the fourth-degree polynomial y(x) that passes through the points-Matlab function?

You can use the polyfit function.x = [0 1 3 5 6]y = [-1 1 3 2 -2]p = polyfit(x, y, 4)You get the coefficients of the polynomial.p = -0.0250 0.2167 -0.8750 2.6833 -1.0000to evaluate tha... Read More »

How to Integrate by Parts when One Function Is a Polynomial?

To integrate by parts you must have two functions multiplied together (in the form of u•dv). The formula to evaluate ∫u•dv is as follows:∫u•dv = uv-∫v•du,

How Do I Graph a Polynomial Function Using a TI-83 Plus Calculator?

The TI-83 Plus graphing calculator allows you to graph and compare functions in addition to adding and updating software applications -- not exactly but similarly to the TI-83, TI-84 and TI-84 Plus... Read More »
