Answer 1

Explanation:

This means that where ever you see x in the function; f(x)= -x-11, you replace it with 9 for the numerator and -6 for the Denominator

=-(9)-11/-(-6)-11

=-9-11÷6-11

=-20÷-5

=4

Answer 2

4

Explanation:

`f(x)=-x-11\\\\(f(9))/(f(-6))\\\\ f(9)= -9-11\\- 20\\\\f(-6) = -(-6)-11\\= 6-11 = -5\\\\\\(f(9))/(f(-6))\\ \\= (-20)/(-5)\\ \\= 4`
