8. The graph of a quadratic function is shown on the grid. -3 -2 -1 -1 1 2 3 4 5 B 7 8 9 -2 -3 ܟ -5 -6 -7 -8 -9 -10 Which function is best represented by this graph? F. Oh(x) = x2 – 3x - 9 G. Oh(x) = x2 + 3x -9 H. Oh(x) = x2 - 6x J. Oh(x) = x2 + 6x​

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

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.  

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
