Find the x-intercepts of the parabola with
vertex (1,-13) and y-intercept (0.-11).
Write your answer in this form: (X1.),(X2,92).
If necessary, round to the nearest hundredth.
Enter the correct answer.

Step-by-step explanation:

we know that

If the vertex is  (1,-13) and the y-intercept is  (0.-11) (y-intercept above the vertex), we have a vertical parabola open upward

The equation of a vertical parabola written in vertex form is equal to

where

a is a coefficient

(h,k) is the vertex

substitute the given value of the vertex

Find the value of a

Remember that we have the y-intercept

For x=0, y=-11

substitute

so

Find the x-intercepts

For y=0

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.
