The directrix of a parabola is the line y=-2 and the focus is (2,-4). This parabola can be written in y=ax^2+bx+c form. Complete the table to determine the values of a, b, and c for the parabola.

Step-by-step explanation:

This calculator will find either the equation of the parabola from the given ... latus rectum, focus, vertex, directrix, focal parameter, x-intercepts, y-intercepts of ... Assume that the equation of the parabola is $$$y=a x^{2} + b x + c$$$. ... Since the parabola passes through the point $$$\left(2, 9\right)$$$, then $$$9=4 a + 2 b + ...

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
