        find f(3) when f(x)=2x=5

$\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

      Write 3 in lieu of x and simplify:-

                           $\Large\text{f(3)=2(3)+5}$

     $\bigstar$ On simplification,

                          $\Large\text{f(3)=6+5}$

$\bigstar$ Which results in

                         $\Large\text{f(3)=11}$

Good luck with your studies! :-)
