In particular, we are interested in locations where graph behavior changes. Polynomials also contain terms with different exponents (for polynomials, these can never be negative). Describe the end behavior and determine a possible degree of the polynomial function in Figure 7. The x-intercepts are found by determining the zeros of the function. The point corresponds to the coordinate pair in which the input value is zero. The leading term is the term containing the highest power of the variable, or the term with the highest degree. When a polynomial is written so that the powers are descending, we say that it is in standard form. The degree is even (4) and the leading coefficient is negative (–3), so the end behavior is. Trinomial A polynomial … The end behavior of the graph tells us this is the graph of an even-degree polynomial. The leading coefficient is the coefficient of the first term in a polynomial in standard form. The y-intercept is the point at which the function has an input value of zero. For any polynomial, the end behavior of the polynomial will match the end behavior of the term of highest degree. Because a polynomial is a function, only one output value corresponds to each input value so there can be only one y-intercept [latex]\left(0,{a}_{0}\right)\\[/latex]. In standard form, the polynomial with the highest value exponent is placed first and is the leading term. Given the polynomial function [latex]f\left(x\right)=\left(x - 2\right)\left(x+1\right)\left(x - 4\right)\\[/latex], written in factored form for your convenience, determine the y– and x-intercepts.
