A circular oil spill continues to increase in size. The radius of the oil spill, in miles, is given by the function r(t) = 0. 5 + 2t, where t is the time in hours. The area of the circular region is given by the function a(r) = πr2, where r is the radius of the circle at time t. Explain how to write a composite function to find the area of the region at time t.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
