area 5x^2+(-8)x+45

area

5 x^{2} + (- 8) x + 45

Unbounded

Solution steps

y = 5 x^{2} + (- 8) x + 45

Rewrite

y = 5 x^{2} + (- 8) x + 45

in the standard form

4 \cdot \frac{1}{20} (y - \frac{209}{5}) = (x - \frac{4}{5})^{2}

Therefore parabola properties are:

(h, k) = (\frac{4}{5}, \frac{209}{5}), p = \frac{1}{20}

Parabola's area is always unbounded

Unbounded

3 x^{2} - 5

y = 28 - 11 x + x^{2}

f (x) = x^{2} - 10 x + 39

(x + 3)^{2} + (3 - x)

- 0.29 x^{2} + 2.5 x
