Trevor is tracking the value of a stock he invested in over the course of one business day (8 hours). The value of the stock can be found by adding these two functions, where t represents time in hours: f(t) = 12(1.20y g(t)=-4.5t Part A Add the two functions and call the resulting function v(t). X2 15px B IV x X, Characters used: 0/15000 .. BB Part B Graph the function you found in part a by going to your math tools and opening the Graph tool. Adjust the scale so that both axes start at 0 and continue far enough to view the polynomial correctly. Part C Using the graph, what was the initial value of the stock?
