Given the function,

We need to find the value of 'x' which makes the function equal to '11'.

This means, we substitute "11" in place of "f(x)" and solve the equation for x. That is our answer(!)

Shown below:

$\begin{gathered} f(x)=2x+1 \\ 11=2x+1 \\ 11-1=2x \\ 10=2x \\ x=(10)/(2) \\ x=5 \end{gathered}$
