axis y=x^2-10x-4

axis

y = x^{2} - 10 x - 4

x = 5

Solution steps

y = x^{2} - 10 x - 4

Rewrite

y = x^{2} - 10 x - 4

in the standard form

4 \cdot \frac{1}{4} (y - (- 29)) = (x - 5)^{2}

Therefore parabola properties are:

(h, k) = (5, - 29), p = \frac{1}{4}

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 = 2 x^{2}

y^{2} = x + 1

y = 2 x^{2} + 5 x - 7

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

y = 3 - x^{2}
