F(x)=2x+1 prove that f(3)-f(0)/f(2)-f(1) =3 ​

Replace x with each value then solve:

f(3) = 2(3) +1 = 7

f(0) = 2(0) +1 = 1

f(2) = 2(2) +1 = 5

f(1) = 2(1) + 1 = 3

Now you have:

7 -1 / 5 -3 = 6/2 = 3

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.
