okay so substitute all x for g(x) value into f(x) function \[\rm f(\color{Red}{g(x)})\] does it make sense ?

not really

alright \[\huge\rm f(\color{ReD}{2x^2+5})=\color{Red}{x}^2+\color{red}{x}+2\] replace all x's with g(x) function which is 2x^2 +5

so then i solve? sorry im trying to get this.

f(2x^2+5) is same as saying f(g(x))
anonymous
  • anonymous
so the answer to this question is f(2x^2+5)??
Nnesha
  • Nnesha
yes right then solve and it's okay plz ask question if you didn' get it:) feel free!

  • anonymous
that would be the answer?
Nnesha
  • Nnesha
yes after that you would get the answer \[\huge\rm f(\color{Red}{g(x)})= (\color{Red}{2x^2+5})^2+(\color{Red}{2x^2+5})+\color{Red}{2}\]

remember (2x2+5)^2 is same as (2x^2+5)(2x^2+5) foil it and then combine like terms :)
