A polynomial function is the sum of monomials (single terms). y=x%5E4+%2B+3x%5E2+%2B+2 is a polynomial.


A Rational function is a faction in which both the numerator and denominator are polynomials. y+=+%28x%5E2+%2B+2x+%2B+3%29+%2F+%28x%5E4+%2B+x%5E3+%2B+3x%29+ is a polynomial.


A quadratic function is a second degree polynomial. In other words, the highest power is 2. x%5E2+%2B+3x+%2B+3 is a quadratic. It is also a polynomial.


A radical function has roots, such as square roots or cube roots. y+=+sqrt%28x%2B4%29 is a radical function.
