Riley is swinging on a swing at the playground. Let trepresent time, in seconds, and let $(t) represent Riley's horizontal distance, in inches, from her starting position, as shown in the table.

Note: When Riley swings in front of the starting position, f(t) is positive, and when Riley swings behind the starting position, f(t) is negative.
From the table, Riley is moving forward on the interval (0,
It takes Riley seconds to swing forward, back, and then return to her starting position.
Riley reaches a maximum distance of
inches from her starting position

its the fourth option

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.
