area y=121-x^2

area

y = 121 - x^{2}

Unbounded

Solution steps

y = 121 - x^{2}

Rewrite

y = 121 - x^{2}

in the standard form:

4 (- \frac{1}{4}) (y - 121) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, 121), p = - \frac{1}{4}

Parabola's area is always unbounded

Unbounded

(5 - x) (x + 2)

f (x) = 2 x^{2} + 3 [- 3, - 1]

x^{2} - 12.4 x + 20

7 x^{2} - 2 x - 20 - (8 x^{2} - 15 x + 20)

\frac{p ^{2}}{16}
