Set the composite results function.


\boldsymbol{f(g(x)) }

Evaluate f(g(x)) by substituting the value of g into f.


\boldsymbol{2(4x+3)-5}

Simplify each term.

Apply the distributive property.


  • \boldsymbol{f(4x+3)=2(4x)+2\cdot3-5 }

Multiply 4 by 2.


  • \boldsymbol{f(4x+3)=8x+2\cdot3-5 }

Multiply 2 by 3.


  • \boldsymbol{f(4x+3)=8x+6-5 }

Subtract 5 from 6.


  • \boldsymbol{f(4x+3)=8x+1 }


\red{\boxed{\green{\boxed{\boldsymbol{\purple{Pisces04}}}}}}
