axis y=3x^2-27

axis

y = 3 x^{2} - 27

x = 0

Solution steps

y = 3 x^{2} - 27

Rewrite

y = 3 x^{2} - 27

in the standard form:

4 \cdot \frac{1}{12} (y - (- 27)) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, - 27), p = \frac{1}{12}

Parabola is of the form

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

and is symmetric around the

y

-axis

Axis of symmetry is a line parallel to the

y

-axis which intersects the vertex:

x = 0

y = 2 x^{2} - 8 x + 8

y = + \frac{1}{7} x^{2}

y = - 8 x^{2} + 4

x = + 2 (y + 1)^{2} - 5

y = x^{2} + 2 x + 3
