Question

Which ordered pair represents a solution to f(x) = x – 5 if f(−1)?

Answer 1

(-1, -6)

Explanation:

f(x) = x - 5

f(x) = -1-5

f(x) = -6

(-1, -6)

Answer 2

For this case we have a function of the form
`y = f (x)`, where
`f (x) = x-5`.

You want to find the value of the function when
`x = -1`.

So:

`f (-1) = - 1-5`

Equal signs are added and the same sign is placed.

`f (-1) = - 6`

Thus, the solution pair, when
`f (-1)`, is:

`(x, y) = (- 1, -6)`

Answer:

`(x, y) = (- 1, -6)`
