Answer 1

`(1)/(64)`

`(1)/(8)`

1

8

64

Explanation:

Basically, you plug the x value that is in the left column into the x in the equation f(x)=8ˣ.

For -2, it would be f(-2)=
`8^(-2)`.

Solve: any number with a negative exponent is 1/[that number], so this would be 1/(
`8^(2)`)

= 1/64 <- because 8*8=64

*The f(-2) or f(x) (or f([any number]) )is just showing the output of the function 8ˣ.

For -1, it would be f(-1)=
`8^(-1)`.

Solve: any number with a negative exponent is 1/[that number], so this would be 1/(
`8^(1)`)

= 1/8 <- because any number to the first power is just that number.

For 0, it would be f(0)=
`8^(0)`.

Solve: any number with an exponent that is zero is just 1

`8^(0)` = 1

For -1, it would be f(1)=
`8^(1)`.

Solve:
`8^(1)` = 8

For -2, it would be f(2)=
`8^(2)`.

Solve:
`8^(2)`

= 64 <- because 8*8=64
