Polynomial functions
A polynomial function is a function such as a quadratic a cubic a quartic Here are some examples of quadratic functions: f(x) = x2 f(x)=2x2 f(x)=5x2 |
Examples of polynomials: 2a + 5b is a polynomial of two terms in two variables a and b. 3xy + 5x + 1 is a polynomial of three terms in two variables x and y. 3y4 + 2y3 + 7y2 – 9y + 3/5 is a polynomial of five terms in two variables x and y.
A polynomial is a function of the form f(x) = anxn + an−1xn−1 + + a2x2 + a1x + a0 .
The degree of a polynomial is the highest power of x in its expression.
Constant (non-zero) polynomials, linear polynomials, quadratics, cubics and quartics are polynomials of degree 0, 1, 2 , 3 and 4 respectively.
