[sdgreen]

The supply of light bulbs is increasing at a constant rate but the sale of light bulbs is increasing even more quickly. Sketcha graph of the situation. Make sure to label evething. Use the TI89 Calculator

Since you are given no numbers, you'll just have to make something up. Draw two lines, with one growing faster than the other.

I can't imagine how one would even begin to use a graphing calculator for this. You might want to ask your instructor how on earth he's expecting you to use it on this exercise.
