what would 6(1/3) be equal to? I'm currently doing Exponential Growth and Decay, but I don't quite understand how to do this one....

The problem is y=6(1/3) exponent x

and it goes from exponent 1-5...

if the exponent is 2, then 6(1/3) exponent 2 would be equal to .66666666.....?

6 x (1/3) = 2

6 x (1/3)^2 = 6/9 = 2/3

etc.

All terms after the first will be repeating decimals. The third term is 2/27 = 0.07407407...and the fourth is 2/81 = 0.024691358024601358024...

It is easier to write them as fractions.

Yes but the only thing is that I then have to graph it as a function...
