Respuesta :

8.6 = -5 
13.6 = 0
There should be another x value in your equation above, but with what you listen this is correct.

Answer:

-5

Step-by-step explanation:

[tex]f(x) = - 5[/tex]

we need to find f(8.6). In f(8.6) the value of x is 8.6

We are given with f(x), to find f(8.6) we plug in 8.6 for x in f(x)

[tex]f(x) = - 5[/tex]

There is no x on the right side

Plug in x with 8.6

[tex]f(8.6) = - 5[/tex]

So, -5 is the answer
