How can I make a general plot like this in Mathematica?

$begingroup$


I want to make two general graphics something like the following.



enter image description here



I want to illustrate the approach to the function by means of a polynomial. I have tried the following.



Plot[{Sin[x] + 2,  Sin[2 x] + 2}, {x, 0, 8}, AxesLabel -> {x, y}, 
Ticks -> {{0.8, 2.4, 4, 5.5, 7.1}, {0, 1, 2, 3}}]


I also want to put $ x_{0}, x_{1}, x_{2},...,x_{n} $ in the points where the graphs differ the most. I appreciate any help.

          Something like this?



              Plot[{Sin[x] + 2, Sin[2 x] + 2}, {x, 0, 8}, AxesLabel -> {x, y}, 
          Ticks -> {{{1, "x[0]"}, {2, "x[1]"}, {3, ""}, {4, "x[3]"}, {5,
          ""}, {6, ""}, {7, "x[n]"}}, None},
          PlotLabels -> Placed[{"y=f(x)", "y=p(x)"}, {Scaled[5], Above}],
          AxesStyle -> Arrowheads[{0.0, 0.05}]]


          enter image description here



          Or



          Plot[{Sin[x] + 2, Sin[2 x] + 2}, {x, 0, 8}, AxesLabel -> {x, y}, 
          Ticks -> {{{1, "x[0]"}, {2, "x[1]"}, {3, ""}, {4, "x[2]"}, {5,
          ""}, {6, ""}, {7, "x[n]"}}, None},
          AxesStyle -> Arrowheads[{0.0, 0.05}],
          Epilog -> {Text[Style["y=f(x)", 22], Scaled[{0.5, 0.9}]],
          Text[Style["y=p(x)", 22], Scaled[{0.25, 0.97}]]}]

            I put the functions Sin [x] +2, Sin [2x] +2 because I did not find others, but I would like others different from mine.
