Explanation: If you were to travel to the desert, the only plants you would find would be shrubs and cacti, because unlike most plants, they are able to survive in a dry climate with very little water. All plants need the basics- that is, sun, water, and CO2, but only a select few have been able to adapt to the harsh desert climate. There are other places in the world where there is intense sunlight all day, (like my front yard, for example, which is ALWAYS yellow smh) but the plants usually are okay as long as they get enough water, which my grass doesn't lol.
A quadratic equation has the general form of:
<span>
y=ax² + bx + c
</span><span>
It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:
</span><span>
y = a(x+h)² - k
</span><span>
where h, k are the vertex points.
</span><span>
y=-2x^2 + 2x+ 2
</span><span>y=-2(x^2 - x) + 2
</span><span>y + 1/4 = -2 (x^2 -x +1/4) + 2
</span><span>y = -2 (x - 1/2)^2 + 7/4
</span><span>
Therefore, the vertex is (-1/2, -7/4)
</span><span>
at x = 6, y = -58</span>
A. once defined, an ecosystem is a unit scientists can analyze.
