1. Quadratic Functions 2A Polynomials

2. A polynomial in x is an expression that contains only non-negative, whole number powers of x. The degree of a polynomial is the highest power of x.

3. Some polynomials

4. Not polynomials

5. General form of a polynomial where n is a positive whole number and a n, a n- 1...a 2, a 1, a 0 are called coefficients (or constants).

6. Value of a polynomial A polynomial may be evaluated by substitution of a number for the variable. For the polynomial, the value of P(x) when x=2 is found by substitution:
