Let the function r(x) = -5(x+3)/ [(x+1)^3)][(x-2)^4](x+3)
a) Explain behavior of r near every value of x that is not in domain of r. Specifically, determine power function of form y= a/(x-h)^p that estimates the behavior and indicate contributions of parameters a, h, and p. Show the behavior with the graph. Give the line of reasoning including suitable calculations to support claims.
