A. f(x)=1/x+4
b. f(x)=1/x-4
c. f(x)=1/x+4
d. f(x)=1/x-4

The correct answer is c. f(x) = 1/(x + 4)

Step-by-step explanation:

We can tell this because as the bottom of the equation (x + 4) approaches 0, the equation gets larger and larger.

Also, you can note that -4 is a asymptote, which can only be from the bottom of the equation being equal to 0. This is only true in option c.  

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.  

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
