To do this we will first need to make sure we have the polynomial in standard form with descending powers. Since the leading coefficient of this odd-degree polynomial is positive, then its end-behavior is going to mimic that of a positive cubic. Section 2. To do this we look at the endpoints of the graph to see if it rises or falls as the value of x increases. Linear functions and functions with odd degrees have opposite end behaviors. Explain what information you need to determine the end behavior of a polynomial function.-If the degree if even or odd (parabola or snake) -If the leading coefficient is positive or negative. Describe the end behavior of the polynomial function in the graph below. The leading term is the term containing that degree, [latex]-{p}^{3}[/latex]; the leading coefficient is the coefficient of that term, [latex]–1[/latex]. Knowing the leading coefficient and degree of a polynomial function is useful when predicting its end behavior. In general, the end behavior of a polynomial function is the same as the end behavior of its leading term, or the term with the largest exponent. If the graph of the polynomial rises left and rises right, then the polynomial […] [latex]\begin{array}{c}f\left(x\right)=2{x}^{3}\cdot 3x+4\hfill \\ g\left(x\right)=-x\left({x}^{2}-4\right)\hfill \\ h\left(x\right)=5\sqrt{x}+2\hfill \end{array}[/latex]. This is going to approach zero. For the function [latex]f\left(x\right)[/latex], the highest power of x is 3, so the degree is 3. Please give me full details. Determine which way the ends of the graph point. Thus, the end behavior of P is similar to x 3: y → −∞ as x → −∞ and y → ∞ as x → ∞ DOWN (left) and UP (right) EXAMPLE: (a) Determine the end behavior of the polynomial P (x) = 3 x 5 − 5 x 3 + 2 x. With end behavior, the only term that matters with the polynomial is the one that has an exponent of largest degree.
