2. A ghost, Big Boo, is drifting up and down erratically as he chases some scared plumbers along a road. The function h gives the height of Big Boo above the road. At position a ( R on the highway, the quantity h(x) is his height relative to the ground. All quantities are measured in metres. Assume h is continuous everywhere and h(0) = 0. Here is the graph of its derivative: y -6 -4 -3 -2 -1 2 09 4 6 y = h'(x) Sketch the graph of h. Remember h(0) = 0 and h is continuous everywhere
