Polynomial functions are expressions that may contain variables of varying degrees, non-zero leading coefficients, positive exponents, and constants. See the polynomial function equation and how to graph it.
Define a polynomial function 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 ...
Graphing a Polynomial Function f (x) = anxn + an-1xn-1 + an-2xn-2 + ¼ + a1x + a0 (an ¹ 0) Use the Leading Coefficient Test to determine the graph's end behavior. Find x-intercepts by setting f (x) = 0 and solving the resulting polynomial equation. If there is an x...

For example, the quartic function f(x) = -2x4 + x3 – 5x2 – 10 has a leading coefficient of -2. The Leading Coefficient Test As x increases or decreases without bound, the graph of the polynomial function f (x) = anxn + an-1xn-1 + an-2xn-2 +…+ a1x + a0 (an 1 0)...

Yes, the zeros are -2 and 1. But you must remember that this is a fifth-degree polynomial. At the -2 zero the graph crosses, but it should be noted that at 1 it only touches at this value. The correct graph would be the following....
To find the zeros of a polynomial function, if it can be factored, factor the function and set each factor equal to zero. Another way to find the x-intercepts of a polynomial function is to graph the function and identify the points where the graph crosses the x-axis. The multiplicity ...
The Stuff Between In order to determine the behavior of the graph between the ends, we need to find two things: The zeros of the function The multiplicity of each zero Finding Zeros To find the zeros of a polynomial function, set the function equal to zero and solve for x. WARNING!!!
Quadratic function(二次函数) is any function of the form: f(x)=ax2+bx+c where a, b, and c are real numbers and a≠0. A quadratic function is a polynomial function whose highest power is 2. Graph is a parabola with vertex at x=−b2a Quadratic function in standard form: f(...
