(-1,5), (0, 0), (1, -1), (2, 0), (3,5)
linear, exponential or neither

I believe it is exponential

Step-by-step explanation:

Plug the points into Desmos graphing calculator and if it forms a parabola then it is exponential.

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.
