parabola graphing help?

Question

how would the graph of the following look like(since u cant exactly graph them here)
1. x=y^2+2 y^2 means y squared
2. x=y^2-2y
3. y=negative radical 4-x(this is underneath the radical and negative is outside

thanks!

Answer 1

1. vertex at (2,0), axis of symmetry is x-axis, opens to the right.
2. x+1 =( y-1)^2 vertex at (-1,1), axis of symmetry is y=1, opens to right
3. y = -sqrt(4-x) vertex at (4,0) axis of symmetry is x-axis, opens to the left.
