    I know how to graph polynomial functions, but i'm having a hard time getting the second point on this one. f(x)=x(x-1)(x+2)(x+2). I graphed my zeros and made the right arrow go up and the left arrow go down. I plotted my first point by pluggin in -1. My

    You did just fine and your second derivative is correct, if you meant (6y^2 - 4x^2)/(9y^3) except they took it a bit further. notice your numerator is -4x^2 + 6y^2 from the original 2x^2 - 3y^2 = 4 , then 4x^2 - 6y^2 = 8 , and -4x^2 + 6y^2 = -8 to get
