To find $(f \circ g)(9)$, first apply $g$ to $9$, which gives $g(9) = \sqrt{9} = 3$. Then, apply $f$ to this result: $f(3) = 3^2 + 9(3) - 7 = 9 + 27 - 7 = 29$.

For the Given Functions F and G, Find the Composition f(x)=x2+9x−7;g(x)=xf ( x ) = x ^ { 2 } + 9 x - 7 ; g ( x ) = \sqrt { x }f(x)=x2+9x−7;g(x)=x​
