Let f be the function defined as follows.(a) Find the differential of f.dy =(b) Use your result from part (a) to find the approx
imate change in y if x changes from 2 to 1.97. (Round your answer to two decimal places.)dy =(c) Find the actual change in y if x changes from 2 to 1.97 and compare your result with that obtained in part (b). (Round your answer to two decimal places.)Δy=
