Thread: Graph the function for an inequality

I'm doing a little practice and came across something I don't quite understand.

This application problem presented me with the equation

which calculates the average retail price (P) of a half-gallon of prepackaged ice cream from 1992-2006. t is the year, with t = 2 corresponding to 1992.

Part of the practice asks me to "Use a graphing utility to graph the function for 2 less than or equal to t less than or equal to 16." I've tried working the numbers around every way I could think and couldn't come up with a graph that matches the one in the back of the book. Currently, I'm trying to set the equation equal to t, however this approach seems vastly more complicated than anything we've done in class.

Any help is appreciated!

It's not asking you to graph an inequality, it's just asking you to graph the function between and ...

Ah. I guess I was getting tired last night. The graph of the solution in my book, though its values are the same as those on my calculator, looked more vertically stretched out, so I thought I was doing something wrong. Silly mistake. Thanks.
