Explanation
[tex]\begin{gathered} f(x)=3x^2+7x-13 \\ g(x)=2x-11 \end{gathered}[/tex]
Step 1
replace the function g(x) in the place the x in f(x)
[tex]\begin{gathered} f(x)=3x^2+7x-13 \\ \\ fog(x)=3(2x-11)^2+7(2x-11)-13 \\ fog(x)=3(4x^2-44x+121)+14x-77-13 \\ fog(x)=12x^2-132x+163+14x-77-13 \\ fog(x)=12x^2-118x+73 \end{gathered}[/tex]I hope this helps you
