axis y=3x^2+6

axis

y = 3 x^{2} + 6

x = 0

Solution steps

y = 3 x^{2} + 6

Rewrite

y = 3 x^{2} + 6

in the standard form:

4 \cdot \frac{1}{12} (y - 6) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, 6), 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} - 6 y - 4 x + 5 = 0

y = 5 x^{2} + x - 3

y = 7 x^{2} + 14 x

f (x) = x^{2} + 6 x + 8

y = 2 x^{2} + 12 x + 10
