area f(x)=2x^2-x-1

area

f (x) = 2 x^{2} - x - 1

Unbounded

Solution steps

y = 2 x^{2} - x - 1

Rewrite

y = 2 x^{2} - x - 1

in the standard form

4 \cdot \frac{1}{8} (y - (- \frac{9}{8})) = (x - \frac{1}{4})^{2}

Therefore parabola properties are:

(h, k) = (\frac{1}{4}, - \frac{9}{8}), p = \frac{1}{8}

Parabola's area is always unbounded

Unbounded

\frac{- 3 x ^{2}}{- 6}

y = 7 x + 8 - x^{2}

2 x^{2} + 12 - 5 x^{2}

17 - x^{2} - (- 19 x + 105)

3 - 4 x^{2}
