What is the axis of symmetry for the function? y = x2 + 3x - 4

y = -2

x = -2

x = -1.5

y = -1.5

what is the vertex for the function? y = x2 - 4x - 3

(-1, 2)

(0, -3)

(1, -6)

(2, -7)

the vertex of y = 9 - 8x - x2 is (-4, 25)

false
true

y=1/4x-4

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.
