f ( x ) = 8 ^ x
x = 0
8 ^ 0 = 1
x = 1
8 ^ 1 = 8
x = 2
8 ^ 2 = 64
x = 3
8 ^ 3 = 512
For the given function, compute the missing values in the following table.
f(x) = 8x
i got the negatives wrong, but I know how to solve for it. Is there a reason it is wrong?
-3: -1/512
-2: -1/64
-1: -1/8
(^These were wrong, but I don't know how to solve it)
0: 1
1: 8
2: 64
3: 512
(^These are correct.)
How should I approach the problem of finding negative exponential values?
Thank you

x = - 1
8 ^ - 1 = 1 / 8
x = - 2
8 ^ - 2 = 1 / 8 ^ 2 = 1 / 64
x = - 3
8 ^ - 3 = 1 / 8 ^ 3 = 1 / 512
8 ^ - 1 = 1 / 8
x = - 2
8 ^ - 2 = 1 / 8 ^ 2 = 1 / 64
x = - 3
8 ^ - 3 = 1 / 8 ^ 3 = 1 / 512
