Question

If f(x)=4x-1 and g(x)=3x-5, what is g(f(2)?

Answer 1

\[f(2)=4\times 2-1=8-1=7\] is a start
now you need \(g(7)\)

Answer 2

\( \color{Black}{\Rightarrow g(4(2) - 1)}\)

\( \color{Black}{\Rightarrow g(8 - 1)}\)

\( \color{Black}{\Rightarrow g(7)}\)

Answer 3

f(2)=4(2)-1
=8-1
=7
g(f(2))=g(7)=3(7)-5
=21-5
=16
