Respuesta :
f(x) = [tex] \sqrt{x+9} [/tex]
g(x) = 8x – 13
f(g(x) = f(8x – 13) = [tex] \sqrt{8x -13 +9} = \sqrt{8x -4} [/tex]
g(x) = 8x – 13
f(g(x) = f(8x – 13) = [tex] \sqrt{8x -13 +9} = \sqrt{8x -4} [/tex]
[tex]f(x)= \sqrt{x+9} [/tex]
[tex]g(x)=8x-13[/tex]
[tex]f(g(x))= \sqrt{g(x)+9}= \sqrt{(8x-13)+9}= \sqrt{8x-4} .[/tex]
[tex]g(x)=8x-13[/tex]
[tex]f(g(x))= \sqrt{g(x)+9}= \sqrt{(8x-13)+9}= \sqrt{8x-4} .[/tex]
