axis y=0.07x^2+20x+350

axis

y = 0.07 x^{2} + 20 x + 350

x = - 142.85714 \dots

Solution steps

y = 0.07 x^{2} + 20 x + 350

Rewrite

y = 0.07 x^{2} + 20 x + 350

in the standard form

4 \cdot 3.57142 \dots (y - (- 1078.57142 \dots)) = (x - (- 142.85714 \dots))^{2}

Therefore parabola properties are:

(h, k) = (- 142.85714 \dots, - 1078.57142 \dots), p = 3.57142 \dots

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 = - 142.85714 \dots

y = (x - 9)^{2} - 2

y^{2} - 8 x - 16 = 0

(x + 7)^{2} = 5 (y + 3)

x \leq + y^{2}

y = - x^{2} + 80 x - 700
