Leading Coefficient
The number in front of the term with the largest degree in a polynomial.
In a polynomial function, the leading coefficient is the coefficient of the term with the highest degree. For example, in the polynomial function f(x) = 5x^3 + 2x^2 – 1, the leading coefficient is 5 because the highest degree term is x^3 and the coefficient for that term is 5.
The leading coefficient of a polynomial function plays an important role in determining the end behavior of the function. If the leading coefficient is positive, then as x becomes very large in either the positive or negative direction, the function will also become very large. On the other hand, if the leading coefficient is negative, then the function will become very negative as x becomes very large in either direction.
Knowing the leading coefficient can also help with determining the number of x-intercepts of the polynomial function. If the leading coefficient is positive, then the function will have the same number of x-intercepts as the degree of the polynomial. If the leading coefficient is negative, then the function will have the same number of x-intercepts as the degree of the polynomial plus or minus an even integer.
In summary, the leading coefficient of a polynomial function can provide important information about the behavior and properties of the function, including the end behavior and number of x-intercepts.
