axis y=3x^2-30x-2

axis

y = 3 x^{2} - 30 x - 2

x = 5

Solution steps

y = 3 x^{2} - 30 x - 2

Rewrite

y = 3 x^{2} - 30 x - 2

in the standard form

4 \cdot \frac{1}{12} (y - (- 77)) = (x - 5)^{2}

Therefore parabola properties are:

(h, k) = (5, - 77), 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 = 5

y = - x^{2} + 4 x - 3

y^{2} - 12 y - 4 x = - 28

25 x^{2} - 10 x - 200 y - 119 = 0

y = x^{2} - 21 x - 4

y = - x^{2} + 150 x - 2000
