Graph both functions on the same coordinate system.

$\displaystyle f(x)=3^{x}$

$\displaystyle f(x)=-3^{x}$

Can somebody help me convert the decimals in the tables into fractions?

1)

x/ f(x)

-3 / .03704

-2 / .11111

-1 / .33333

0 / 1

1 / 3

2 / 9

3 / 27

2)

x/ g(x)

-3/ -.037

-2/ -.1111

-1/ -.3333

0/ -1

1/ -3

2/ -9

3/ -27

Also...are these tables for the functions correct?

Thanks in advance!
