2.  A polynomial function has the form  where are real numbers and n is a nonnegative integer. In other words, a polynomial is the sum of one or more monomials with real coefficients and nonnegative integer exponents. The degree of the polynomial function is the highest value for n where a n is not equal to 0. Polynomial functions of only one term are called monomials or power functions.

10.  Do problems 23-25 from book page 96

13.  Do problems 49 and 51 from book page 97

14.  What is the minimum value?  When the parabola opens upward, the y-value of the vertex is the minimum value.  What is the maximum value?  When the parabola opens downward the y- value of the vertex is the maximum value.

16.  Find the minimum or maximum value of f(x) = –3x 2 + 2x – 4.  Solution:  Step 1 Determine whether the function has minimum or maximum value.  Because a is negative, the graph opens downward and has a maximum value.  Step 2 Find the x-value of the vertex.

17.  Step 3 Then find the y-value of the vertex,  The maximum value is -11/3

18.  Find the minimum or maximum value of f(x) = 6x 2 + 5x – 4.

20.  Do problems 24-27 and 33 and 36 from page 96

21.  Today we learned about quadratic equations  Next time we are going to continue with 2.3
