A polynomial function can be written as (x + 1)(x + 4)(x − 7). What are the x-intercepts of the graph of this function? (4 points)
(1, 0), (4, 0), (7, 0)
(−1, 0), (−4, 0), (−7, 0)
(1, 0), (4, 0), (−7, 0)
(−1, 0), (−4, 0), (7, 0)

tube or goog would be a great resource to with that question

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.
