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! :-)
