Answer 1

Answer: f(-6) =
`-(12)/(11)`, f(-4) =
`(4)/(3)`, f(6) =
`(12)/(11)`

Explanation:

#1 - 7 and 9 are correct but 8 is wrong:

f(x) =
`(2x)/(x^(2)-25)`

f(-6) =
`(2(-6))/((-6)^(2)-25)`

=
`(-12)/(36-25)`

=
`(-12)/(11)`

f(-4) =
`(2(-4))/((-4)^(2)-25)`

=
`(-8)/(16-25)`

=
`(-12)/(-9)`

=
`(4)/(3)`

f(6) =
`(2(6))/((6)^(2)-25)`

=
`(12)/(36-25)`

=
`(12)/(11)`
