[1.6]g(x)=2x^2-x

[1.6] g (x) = 2 x^{2} - x

(h, k) = (0.25, - 0.078125), p = 0.2

Solution steps

[1.6] y = 2 x^{2} - x

Rewrite

[1.6] y = 2 x^{2} - x

in the standard form

4 \cdot 0.2 (y - (- 0.078125)) = (x - 0.25)^{2}

Therefore parabola properties are:

(h, k) = (0.25, - 0.078125), p = 0.2

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

16 x^{2} + 72 x - 112 y = - 221

- x^{2} + 12 x + 24 y = 132

xx = 4 + 3 y

y^{2} - 10 y - 4 x + 25 = 0
