Find  ( g \circ f ) ( 3 )  where  f ( x ) = 2 x - 11  and  g ( x ) = \sqrt { x + 6 }  . A)-16 B)2 C)1 D)-15 E)-5

jaqueline Lozano · Accepted Answer

Final Answer : C, Explanation :   First, apply  f  to 3:  f(3) = 2(3) - 11 = 6 - 11 = -5 . Then, apply  g  to this result:  g(-5) = \sqrt{-5 + 6} = \sqrt{1} = 1 .
