Math question on exponential functions? can't figure out how to enter in calculator?

What kind of calculator are you using? If you are using any of the TI calculators, you just enter in exactly what you see. To enter it into Y1=, you find the little on on the very top, left corner, and press it. Then you enter in exactly what you see into the first line which says Y1=. To find the table, 2ND press the on that has the word TABLE over it. :D
