axis y=5*(x+7+sqrt(149))(x+7-sqrt(149))

axis

y = 5 \cdot (x + 7 + 149) (x + 7 - 149)

x = - 7

Solution steps

y = 5 (x + 7 + 149) (x + 7 - 149)

Rewrite

y = 5 (x + 7 + 149) (x + 7 - 149)

in the standard form

4 \cdot \frac{1}{20} (y - (- 745)) = (x - (- 7))^{2}

Therefore parabola properties are:

(h, k) = (- 7, - 745), p = \frac{1}{20}

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 = - 7

30 x^{2} + 90 x + y + 64 = 0

y = (x - 7) (x - 9)

y = (3 x - 4) (4 x - 3) - 2 x

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

y = x^{2} - 15 x
