Explain why the derivative function of the function g(x) = x is equal to 1 on the interval (0,&#8734;), equal to 1 on the interval
(-&#8734;,0), and undefined at 0. [Hint. Sketch the graph of g.]

Consider the region R bounded by the curve xy =3 and the lines x I and x =4. Set up the integrals (do not evaluate) that give the following
The area of the region R
The solid generated by rotating the region R around the x-axis. Indicate the method you are using.
The solid generated by rotating the region R around the y-axis. Indicate the method you are using.
