Case 4 The graph on the right is defined by yax+ 2x + 138-14x24 or in factored form y = -(x + 3)(x + 1)(x - 2)(x-4) Questions: a. Is the leading coefficient a positive or a negative number? b. Is the polynomial of even degree or odd degree? c. Observe the end behaviors of the graph on both sides. Is it rising or falling to the left or to the right?​
