Which statement best describes the graph of x3 − 3x2 − x + 3? It starts down on the left and goes up on the right and intersects the x-axis at x = −1, 2, and 3. It starts down on the left and goes up on the right and intersects the x-axis at x = −1, 1, and 3. It starts up on the left and goes down on the right and intersects the x-axis at x = −1, 2, and 3. It starts up on the left and goes down on the right and intersects the x-axis at x = −1, 1, and 3.

    when highest degree is odd then if leading coefficient is positive right side will rise , left end will fall AND if leading coefficient is negative then right end will fall and left end will rise so leading coefficient is negative or positive ?

    are you allowed to graph it ? if yes then point where line cross x-axis is x-intercept

    its just multiple choice so I have to pick an answer but i can try graphing it

    okay or you can substitute y for 0 to find x-intercept

    Im think B is correct if I did my graph right

    graphing is good but you don't really need after that info if leading coefficient is positive then left side will fall and right side will rise
