Derivate f(x)=x^3-2x^2-x+1

f(x)'=3x^2-4x

Step-by-step explanation:

dy/ dx or f(x)'=3x^2-4x

Please make answer as brainliest

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.
