A) $\frac { f ( 6 + h ) - f ( 6 ) } { h } = h + 11$ , h $\neq$ 0
B) $\frac { f ( 6 + h ) - f ( 6 ) } { h } = h + 15$ , h $\neq$ 0
C) $\frac { f ( 6 + h ) - f ( 6 ) } { h } = h + 14$ , h $\neq$ 0
D) $\frac { f ( 6 + h ) - f ( 6 ) } { h } = h + 12$ , h $\neq$ 0
E) $\frac { f ( 6 + h ) - f ( 6 ) } { h } = h + 13$ , h $\neq$ 0
