6. (10 points) Consider the polynomial that is graphed below. Answer the following questions based on the graph. To receive full credit you must explain your answers for parts a, b, and c and show your work for part d. dib a. Is the degree of this polynomial even or odd? Why? b. Will the leading term be positive or negative? Why? 0. List the roots and their possible multiplicities for this function. How do you know? d. Write a possible function in factored form for this graph. Use the letter k in place of the leading coefficient, because you don't know what that is yet. e. The y-intercept is at the point (0, 0.9). Use this information to find the leading coefcient. Then rewrite the function with this value in place. Show your work
