Find the rule for the function x, -1, 0, 1, 2 y, 3, 1, 1/3, 1/9

The function is y =

This can be found by using the base equation for exponential y = . Now we can use the second ordered pair (0, 1) to find the value of a.

y =

1 =

1 = a(1)

1 = a

Now that we have a, we can solve for b using any other ordered pair.

y =

=

= (1)(b)

= b

Now we can use these in the same equation.

y =
