Keep in mind that for any polynomial, there is only one leading coefficient. The x-intercepts occur at the input values that correspond to an output value of zero. The leading coefficient is the coefficient of that term, –4. The first term has coefficient 3, indeterminate x, and exponent 2. We can describe the end behavior symbolically by writing. The leading term is the term containing the highest power of the variable, or the term with the highest degree. The leading term of f (x) is anxn, where n is the highest exponent of the polynomial. In a polynomial function, the leading coefficient (LC) is in the term with the highest power of x (called the leading term). The leading coefficient here is 3. Although the order of the terms in the polynomial function is not important for performing operations, we typically arrange the terms in descending order of power, or in general form. The first term has an exponent of 2; the second term has an \"understood\" exponent of 1 (which customarily is not included); and the last term doesn't have any variable at all, so exponents aren't an issue. 2. Leading Term of a Polynomial Calculator is an instant online tool that calculates the leading term & coefficient of a polynomial by just taking the input polynomial. We can see these intercepts on the graph of the function shown in Figure 12. --Here highest degree is maximum of all degrees of terms i.e 1 .--Hence the leading term of the polynomial will be the terms having highest degree i.e ( 14 a, \ 20 c) .--14 a has coefficient 14 .--20 c has coefficient 20 . The leading coefficient of a polynomial is the coefficient of the leading term.
