  1. Students, Take out your calendar and your homework. Take out your spiral notebook and Complete the DNA.Use your notes if necessary. Find the x-intercepts of the following functions. (Hint: set each function equal to zero and solve.) Multiply each expression.

  2. Real Zeros of Polynomial Functions If f is a polynomial function and a is real, the following are equivalent:

  3. 3) Find all the real zeros of

  4. (4) a) Find all real zeros of Hint: multiply by – 4 b) Find the relative extrema of f. The relative minima and maxima.

  5. 5) Find all real zeros of

  6. Find polynomial functions with the following zeros.

  7. Leading Coefficient Test 1. When n is odd: If the leading coefficient is positive If the leading coefficient is negative Then the graph falls to the left and rises to the right. Then the graph risesto the left and fallsto the right.

  8. Leading Coefficient Test 2. When n is even: If the leading coefficient is positive If the leading coefficient is negative Then the graph risesto the left and right. Then the graph fallsto the left and right.

  9. Describe the left-hand and right-hand behavior of the graph of each function. The degree is odd and the leading coefficient is positive. The graph falls to the left and rises to the right. The degree is even and the leading coefficient is negative. The graph falls to the left and right.

  10. The numbers of new accounts opened at a credit union in the years 2001 and 2006 can be approximated by the model: with t = 11 corresponding to 2001. Using this model, determine the year in which the number of new accounts opened was greatest.
