I have this problem.
You buy a personal watercraft for $8100
The depreciated value y after t years is y = 8100-929(t), for 0
(a) Use the constraints of the model to graph the equation using an appropriate viewing window.
(b) Use the zoom and trace features of a graphing utility to determine the value of t when y = 5545.25. Verify your answer algebraically.
(c) Use the value feature or the zoom and trace features of a graphing utility to determine the value of y when t = 5.5. Verify your answer algebraically.
Which graphing utility should I use. I have mathGV and graphmatica. But don't know how to see the graph since the y values are very high .
Any one can help please?:confused:
I drew the graph in graphmatica. Given below.
But how to find the t value when y=5545.25 from the graph?
seems very difficult.
Try Graph by Ivan Johannsen (Download here)

You should then be able to get a suitable view of the bit of the graph that you want.
