area 0.9x^2+6.4x+7.7

area

0.9 x^{2} + 6.4 x + 7.7

Unbounded

Solution steps

y = 0.9 x^{2} + 6.4 x + 7.7

Rewrite

y = 0.9 x^{2} + 6.4 x + 7.7

in the standard form

4 \cdot 0.27777 \dots (y - (- 3.67777 \dots)) = (x - (- 3.55555 \dots))^{2}

Therefore parabola properties are:

(h, k) = (- 3.55555 \dots, - 3.67777 \dots), p = 0.27777 \dots

Parabola's area is always unbounded

Unbounded

x = y^{2} + 2

169 c m^{2}

f (x) = 6 x^{2}

f (120) = - \frac{1}{480} x^{2} + 30
