Let y = f(x) be a particular solution of the differential equation dy/dx = 1 / xy with f(1) = 2. (a) Find d2y dx2 at the point (1, 2).
(b) Write an equation for the line tangent to the graph of f at (1, 2) and use it to approximate f(1.1). Is the approximation for f(1.1) greater than or less than f(1.1)? Explain your reasoning.
(c) Find the solution of the given differential equation that satisfies the initial condition f(1) = 2.

Luke started a weight-loss program. the first week, he lost x pounds. the second week, he lost pounds less than times the pounds he lost the first week. the third week, he lost 1 pound more than of the pounds he lost the first week. liam started a weight-loss program when luke did. the first week, he lost 1 pound less than times the pounds luke lost the first week. the second week, he lost 4 pounds less than times the pounds luke lost the first week. the third week, he lost pound more than times the pounds luke lost the first week.
