Write the Function F(x) as a Composition of F, G

Multiple Choice

Write the function F(x) as a composition of f, g, or h.
- $\begin{array} { l } \mathrm { f } ( \mathrm { x } ) = \mathrm { x } ^ { 2 } - 8 \quad \mathrm {~g} ( \mathrm { x } ) = - 3 \mathrm { x } \quad \mathrm { h } ( \mathrm { x } ) = \sqrt { \mathrm { x } + 5 } \\\mathrm {~F} ( \mathrm { x } ) = \sqrt { \mathrm { x } ^ { 2 } - 3 }\end{array}$

A) $\mathrm { F } ( \mathrm { x } ) = ( h \circ f ) ( \mathrm { x } )$
B) $F ( x ) = ( h \circ g ) ( x )$
C) $F ( x ) = ( f \circ h ) ( x )$
D) $\mathrm { F } ( \mathrm { x } ) = ( \mathrm { g } \circ \mathrm { h } ) ( \mathrm { x } )$
