axis y=x^2-8

axis

y = x^{2} - 8

x = 0

Solution steps

y = x^{2} - 8

Rewrite

y = x^{2} - 8

in the standard form:

4 \cdot \frac{1}{4} (y - (- 8)) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, - 8), 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 = 0

y = \frac{1}{17} (x + 5)^{2}

y = x^{2} + 100

x^{2} - 8 x + 14

f (x) = x^{2} - 18 x + 80

y = lo g_{5} (2) x^{2}
