Question

Given the function below, find /(-7)
(X) = -2x-1

Answer 1

For this case we have a function of the form
`y = f (x)`where:

`f (x) = - 2x-1`

We must find the value of the function when
`x = -7`. So:

`f (-7) = - 2 (-7) -1`

By definition we have to:

`- * - = +\\f (-7) = 14-1 = 13`

Thus, the value of the function is
`y = 13`

Answer:

`y = f (-7) = 13`
