For this case we have a function of the form[tex]y = f (x)[/tex], where [tex]f (x) = x-5[/tex].
You want to find the value of the function when[tex]x = -1[/tex].
So:
[tex]f (-1) = - 1-5[/tex]
Equal signs are added and the same sign is placed.
[tex]f (-1) = - 6[/tex]
Thus, the solution pair, when[tex]f (-1)[/tex], is:
[tex](x, y) = (- 1, -6)[/tex]
Answer:
[tex](x, y) = (- 1, -6)[/tex]
