Solve the Problem $f ( x ) = - x - 6$

Solve the problem.
-Suppose that $f ( x ) = - x - 6$ and $g ( x ) = x - 11$ .
(a) Solve $f ( x ) = 0$ .
(b) Solve $g ( x ) = 0$ .
(c) Solve $f ( x ) = g ( x )$ .

A) (a) $x = 6 ;$ (b) $x = 11 ;$ (c) $x = 2.5$

B) $( \mathrm { a } ) \mathrm { x } = - 6$ ;
(b) $x = 11$
(c) $x = 2.5$

C) (a) $x = - 6$ ;
$( b ) x = 11$
(c) $x = - 8.5$

D) (a) $x = - 6$ ;
(b) $x = - 11$
(c) $x = 2.5$
