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(1.20)^t
g(t)=-4.5t

a. Add the two functions and call the resulting function (v(t)
b. Graph the function you found. Adjust the scale so that both axes start at 0 and continue far enough to view the polynomial correctly.
c. using the graph, what was the initial value of the stock?
d. About what was the final value of the stock for the day.
e. Does the value of the stock increase or decrease from where it started in the day? By about how much?
f. About when was the value of the stock at its lowest, and what was its value?
