Let J be the region in the first quadrant bounded by the x-axis, the curve y = √x, and the line x = 9. 1. Set up an integral expression that finds the volume of the solid formed by revolving region J bounded about x-axis.
2. Set up an integral expression that finds the volume of the solid formed by revolving region J bounded about the line x = 9.

Part a: explain why the x-coordinates of the points where the graphs of the equations y = 2−x and y = 8x+4 intersect are the solutions of the equation 2−x = 8x+4. (4 points) part b: make tables to find the solution to 2−x = 8x+4. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 2−x = 8x+4 graphically? (2 points)
