Which of the following is an example of urbanization? A. A city's population decreases as people move from its suburbs to
rural areas.
B. A city's population stays the same as people move from its central
business district to its suburbs.
C. A city's population increases as people move from rural areas to
its suburbs
D. A city's population stays the same as people move from its
suburbs to its central business district.

Either c or d, I would lean more towards c but d is a definite possibility

I think it’s D because the other ones only talk about moving to rural or suburban areas which wouldn’t be right

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
