Question 1093683
Your given function appears graphed like {{{graph(300,300,-5,5,-5,5,2x+1)}}}.


If you reflect that line through {{{y=x}}}, then the resulting reflection is {{{y=x/2-1/2}}}.
{{{graph(300,300,-5,5,-5,5,2x+1,x,x/2-1/2)}}} and the purple line is the inverse for your given f(x).


None of your choices match the inverse of f(x).
