Help! I have an assignment to do, and I need to figure out how to create a graph that shows several linear functions, i.e. y = x for x between 0 and 10, y = 0.5x for 10 < x <20, and y = 3x for x >= 20. Note that I only want to show the function for the relevant range; I don't want all the graphs crossing the y-axis. Anyone have any thoughts? Can this be done in Excel? Really appreciate it! I've got to get some sleep now, but I will check back ASAP and shower praise on anyone who can help me out. Thanks!
