Question

Digamos que f ( x ) = 3 x + 1 y g ( x ) = 2 x – 3.  

             Encuentre f ( g ( x )) y g ( f ( x )). 


​

Answer 1

Respuesta:

Explicación paso a paso:

f ( x ) = 3 x + 1

g ( x ) = 2 x – 3.  

f ( g ( x )) = 3[(2x-3)] + 1

f ( g ( x )) = 6x - 9 +1

f ( g ( x )) = 6x - 8

g ( f ( x )) = 2[(3x+1)] - 3

g ( f ( x )) = 6x + 2 - 3

g ( f ( x )) = 6x - 1
