estimate the value of the function at x = 2 given the following graph.

The answer to your question is: F(2) = 3

Step-by-step explanation:

When x = 2, what is the value of f(x)

Just look in the graph 2 in the x-axis and in the red line look for the value of the graph.

Notice that when x = 2 f(x) = 3

1 is c

2 is a

3 is a

step-by-step explanation:

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.
