If point p(2,-4) is reflected over the x-axis, determine the coordinates of the image.

(-4, 2)
(4, 2)
(2, 4)
(-2, -4)

The answer is (2,4)

Hi! here the notation for a point is (x,y), so a reflection over the x axis will turn a point (x,y) in a reflected point (x, -y). This means that you change y for -y, and x stays the same.

Then if we have the point (2,-4), after the reflection in the x axis, we will get (2,-(-4)) = (2,4)

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.
