    關(guān)于高次多項(xiàng)式函數(shù)的圖像問題
    High-degree polynomial function:
    If n (the highest exponent)is odd,and An>0,the graph falls to the left and rises to the right.
    If n is odd,and An<0,the graph rises to the left and falls to the right.
    If n is even,and An >0,the graph rises to the left and right
    If n is even,and An<0,the graph falls to the left and right
    An 是最高次項(xiàng)的系數(shù)
    這里該怎么理解?

    優(yōu)質(zhì)解答
    如果n(最高次)是偶數(shù),并且An(最高項(xiàng)系數(shù))>0,那么圖像左邊下降,右邊上升;
    如果n是偶數(shù)且An0,那么圖像從左到右都上升
    如果n是奇數(shù)且An
