-$f ( x ) = \sqrt { x + 7 } , g ( x ) = 8 x - 11 ; \quad$ Find the function $f \circ g$.
A) $8 \sqrt { x + 7 } - 11$
B) $2 \sqrt { 2 x - 1 }$
C) $8 \sqrt { x - 4 }$
D) $2 \sqrt { 2 x + 1 }$

The composite function $f \circ g$ is $f(g(x)) = \sqrt{8x - 11 + 7} = \sqrt{8x - 4} = 2\sqrt{2x - 1}$.

For the Given Functions F and G, Find the Requested f(x)=x+7,g(x)=8x−11;f ( x ) = \sqrt { x + 7 } , g ( x ) = 8 x - 11 ; \quadf(x)=x+7​,g(x)=8x−11;
