axis x=+(y+1)^2

axis

x = + (y + 1)^{2}

y = - 1

Solution steps

x = (y + 1)^{2}

Rewrite

x = (y + 1)^{2}

in the standard form:

4 \cdot \frac{1}{4} (x - 0) = (y - (- 1))^{2}

Therefore parabola properties are:

(h, k) = (0, - 1), p = \frac{1}{4}

Parabola is of the form

4 p (x - h) = (y - k)^{2}

and is symmetric around the

x

-axis

Axis of symmetry is a line parallel to the

x

-axis which intersects the vertex:

y = - 1

- y^{2} + x + 6 y - 14 = 0

y = x^{2} + x - 9

2 y^{2} - x - 12 y + 18 = 0

y = (x + 6) (x - 2)

x = (y + 2) (y - 3)
