    (u-shaped) : y= 8x²-4x+2
    (mountain-shaped) : y= -3x²+10x-5

    y=2x^2+4x+3
    this will produce a u-shaped graph

    y=-4x^2+5x-2
    this will produce a mountain shaped graph

    U-shaped curve
    y = x^2+2x+5

    Mountain-shaped cuve
    y = -3x^2+5x+6

    y = 2x^2 - 6x + 5 <- U-shaped curve
    y = -7x^2 + 3x - 20 <-- mountain shaped curve

    y=-5x^2+3x-7 will give a mountain shape
    y= 3x^2+8x-6 will give a U shape

    3x^2+7x+3 = U- shaped curve
    5x^2+6x=1 = Mountain- shaped curve

    U-shaped: x^2 + x + 1
    Mountain-shaped: -x^2 + 2x + 2

    U shaped curve:

    y = 42x^2 + 41x + 83

    Mountain shaped curve:

    y = -21x^2 + 20.5 - 1.5

    y= 3x^2 + 2x + 1 will give a U-shape curve
    y= -3x^2 + 5x + 19 will give a mountain shape curve
