The leading coefficient is the coefficient of the first term in a polynomial in standard form. 2x 2, a 2, xyz 2). A General Note: Terminology of Polynomial Functions We often rearrange polynomials so that the powers on the variable are descending. The leading term of f (x) is anxn, where n is the highest exponent of the polynomial. Another way to describe it (which is where this term gets its name) is that; if we arrange the polynomial from highest to lowest power, than the first term is the so-called ‘leading term’. You can calculate the leading term value by finding the highest degree of the variable occurs in the given polynomial. This means the graph has at most one fewer turning point than the degree of the polynomial or one fewer than the number of factors. To determine when the output is zero, we will need to factor the polynomial. The degree of the polynomial is the highest power of the variable that occurs in the polynomial; it is the power of the first variable if the function is in general form. The y-intercept occurs when the input is zero. In this video, we find the leading term of a polynomial given to us in factored form. The leading term is the term containing that degree, [latex]-{p}^{3}\\[/latex]; the leading coefficient is the coefficient of that term, –1. The end behavior of the graph tells us this is the graph of an even-degree polynomial. In standard form, the polynomial with the highest value exponent is placed first and is the leading term. We can see these intercepts on the graph of the function shown in Figure 12. Or one variable. The degree is 3 so the graph has at most 2 turning points. Have an insight into details like what it is and how to solve the leading term and coefficient of a polynomial equation manually in detailed steps. The leading coefficient of a polynomial is the coefficient of the leading term. The leading term is the term containing the highest power of the variable, or the term with the highest degree.

The term in the polynomials with the highest degree is called a leading term of a polynomial and its respective coefficient is known as the leading coefficient of a polynomial. In addition to the end behavior of polynomial functions, we are also interested in what happens in the “middle” of the function. The largest exponent is the degree of the polynomial. Polynomials also contain terms with different exponents (for polynomials, these can never be negative). The degree is even (4) and the leading coefficient is negative (–3), so the end behavior is. Given a polynomial … When a polynomial is written so that the powers are descending, we say that it is in standard form. The leading term is the term containing that degree, [latex]5{t}^{5}\\[/latex]. It is possible to have more than one x-intercept. Example: 21 is a polynomial.
