A line that a function approaches but never intersects.
The line of symmetry of a parabola.
A polynomial function of degree zero in which the constant term ≠ 0.
The coefficient of x^{0} in a polynomial.
The value of n in a polynomial f (x) = a_{n}x^{n} + a_{n-1}x^{n-1} + ^{ ... } + a_{1}x + a_{0}, where a_{n}≠ 0. If f (x) = 0, then the degree is undefined.
Descartes' Rule of Signs states that the number of positive real roots is less than or equal to the number of variations in the function f (x). It also states that the number of negative real roots is less than or equal to the number of variations in the function f (- x).
The value of a_{n} in a polynomial f (x) = a_{n}x^{n} + a_{n-1}x^{n-1} + ^{ ... } + a_{1}x + a_{0}, where a_{n}≠ 0 unless f (x) = 0.
A first-degree polynomial.
If (x - c)^{n} is a factor of a polynomial but (x - c)^{n+1} is not, the root c is said to be a root of multiplicity n.
Another name for the graph of a quadratic function.
An expression of one variable of the form a_{n}x^{n} + a_{n-1}x^{n-1} + ^{ ... } + a_{2}x^{2} + a_{1}x + a_{0}, where a_{n}, a_{n-1},..., a_{1}, a_{0} are real numbers, n is a nonnegative integer, and a_{n}≠ 0.
A function that is defined by a polynomial; it is of the form f (x) = a_{n}x^{n} + a_{n-1}x^{n-1} + ^{ ... } + a_{2}x^{2} + a_{1}x + a_{0}, where a_{n}, a_{n-1},…, a_{1}, a_{0} are real numbers, n is a nonnegative integer, and a_{n}≠ 0.
A second-degree polynomial.
A function which can be expressed as the quotient of two polynomial functions.
The Rational Root Theorem is a useful tool in finding the roots of a polynomial function f (x) = a_{n}x^{n} + a_{n-1}x^{n-1} + ... + a_{2}x^{2} + a_{1}x + a_{0}. If the coefficients of a polynomial are all integers, and a root of the polynomial is rational (it can be expressed as a fraction in lowest terms), the Rational Root Theorem states that the numerator of the root is a factor of a_{0} and the denominator of the root is a factor of a_{n}.
Values of the independent variable for which a polynomial function equals zero.
Consecutive terms of a polynomial whose coefficients have opposite signs.
The point on a parabola at which the quadratic function reaches its minimum or maximum value.
The polynomial f (x) = 0.
