3. Polynomial Polynomial- a monomial or a sum of monomials Polynomial function- a function of the form Leading coefficient- a n Degree- n Constant term- a 0 Standard Form-terms are written in descending order of exponents from left to right

4. Common Polynomial Functions

5. Ex. Decide whether the function is a polynomial function. If so, write it in standard form and state its degree, type, and leading coefficient.

6. Ex. Use direct substitution to evaluate f(x) = 2x 4 – 5x 3 – 4x + 8 when x = 3.

7. Ex. Use direct substitution to evaluate the polynomial function for the given value of x. f(x)=x 4 + 2x 3 + 3x 2 – 7; x = -2

8. Ex. Use synthetic division to evaluate f(x) = 2x 4 – 5x 3 – 4x + 8 when x = 3
