Students, Take out your calendar and your homework 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. 3) Graph the following function on your calculator. Use CALC to find any relative extrema and zeros.

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 rises to the left and falls to the right.

Leading Coefficient Test 2. When n is even: If the leading coefficient is positive If the leading coefficient is negative Then the graph rises to the left and right. Then the graph falls to the left and right.

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.

Repeated Zeros Let’s check ------
