Describing each stage in the demographic transition model using cbr, cdr, nir. characterize the amount of growth of each stage (low, high, aka moderate).

Stage 1
     Low Growth
     Very high CBR, Very high CDR, Very low NIR
Stage 2
     High Growth
     High CBR, Rapidly declining CDR, Very high NIR
Stage 3
     Moderate Growth
     Rapidly declining CBR, Moderately declining CDR, Moderate NIR
Stage 4
     Low Growth
     Very low CBR, Low or slightly increasing CDR, zero or negative NIR

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing
