- LIFE SCIENCE APPLICATIONS APPLY IT Splenic Artery Resistance Blood flow to the fetal spleen is of research interest because several diseases are associated with increased resistance in the splenic artery the artery that goes to the spleen. Researchers have found that the index of splenic artery resistance in the fetus can be described by the function y=0.057x0.001x2, where x is the number of weeks of gestation. Source: American Journal of Obstetrics and Gynecology. a. At how many weeks is the splenic artery resistance a maximum? b. What is the maximum splenic artery resistance? c. At how many weeks is the splenic artery resistance equal to 0, according to this formula? Is your answer reasonable for this function? Explain.arrow_forwardNumerical Analysis In Exercises 37-40, In this question, (a) determine the domains of fand g, (b) simplify fand find any vertical asymptotes of the graph of f, (c) complete the table, and (d) explain how the two functions differ. f(x)=2x8x29x+20,g(x)=2x5arrow_forwardUsing Technology In Exercises 49-52, (a). use a graphing utility to graph the function, (b) use the graph to approximate any x-intercepts of the graph, (c) find any real zeros of the function algebraically, and (d) compare the results of part (c) with those of part (b). y=4x320x2+25xarrow_forward
