Find the parabola opening down
1. x = -1/8 y^2
2. y = -1/4 x^2
3. y = 1/8 x^2
4. x = 1/8 y^2
And find the parabola opening to the left:
1. x = -1/8 y^2
2. y = -1/4 x^2
3. y = 1/8 x^2
4. x = 1/8 y^2
if it is x^2 it will be a up or down parabola.
if it is y^2 it will be a left or right parabola
if the coefficient of the squared term is positive then it will open in the positive direction
if the coefficient of the squared term is negative then it will open in the negative direction
if it is x^2 it will be a up or down parabola.
if it is y^2 it will be a left or right parabola
if the coefficient of the squared term is positive then it will open in the positive direction
if the coefficient of the squared term is negative then it will open in the negative direction
