Unformatted text preview: b.) Substance X is converted into substance Y at a rate that, at any time t, is proportional to the cube of the amount of X. Set up the differential equation whose solution is y = f(t), the amount of substance X at time t. Sketch both the yz-graph and the graph of the solution. Label all graphs. 7.)
