10) Find the volume V of the solid formed by rotating the area R about the x-axis. 9 pts R is given by the area between the x-axis and the curve f(x) = - = * + 2 2 State the general volume formula from the lecture notes, then use it. (Give the exact solution, NOT an approximation!) 1 1) a) Solve the initial value problem. Only use notation from lecture notes to get credit. 5 pts dx Y = e-2x wherey = 4 when x = 0 b) Explain every step together with a) 2 pts
