Graph the polynomial function f(x)=(x-1)^2(x+ 2)^3.Solution:The zeros are -2 and 1, and therefore, the x-intercepts are (-2, 0) and (1,0).The y-intercept is (0, 8).Plotting these points and connecting with a smooth curve yields the graph....
Identify the end behavior of the graph of a polynomial function based on the degree of the function and the sign of the leading coefficient Define zeros of a function Explain the relationship between zeros and xx-intercepts on the graph of the function Explain the relationship between the degree...
It's usually best to draw a graph of the function and determine the roots from where the graph cuts thex-axis. Let's see how that works. Solution 1: Graphically.The roots are given by thex-intercepts. f(x) =x4−x3− 19x2− 11x+ 31 ...
How to Find the Zeros of a Polynomial Function? Thezeros of a polynomial functionf(x) are also known as its roots or x-intercepts. Here are the steps to find them: Set it equal to zero. i.e., f(x) = 0. Solve the equation. ...

Sketch the graph of the polynomial functionP(x)=−2x(x−2)2 Graph of Function: When the two variable functions is plotted in the Cartesian plane, then it may have extrema point, the inflection point, x-intercepts, and y-intercepts etc. Also, we can make use of calculus to...
Find the Zeros of the polynomial function Since the degree of the polynomial is four, we must find four Zeros, not necessarily distinct. We can factor the equation as follows : The Zeros are -3, 3, -i, and i. The two real Zeros are the x-intercepts of the function. The two imagi...
Let us put this all together and look at the steps required to graph polynomial functions. How To: Given a polynomial function, sketch the graph. Find the intercepts. Check for symmetry. If the function is an even function, its graph is symmetrical about the y-axis, that is, f(–x) ...
