How to draw this graph?

I want to draw something like this example, I mean without numbers in the axis but just x0 and x1, and with the functions shown only between x0 and x1.

Read about xticks for labelling x1, x2 along the axes. I have taken random points for plotting. You can take your required points to plot striaght line and the curve.

% Striaght line 
L = rand(2,2) ; 
% Curve passing through above two points 
p = polyfit(L(:,1),L(:,2),3) ; 
xi = linspace(min(L(:,1)),max(L(:,1))) ; 
yi = polyval(p,xi) ; 
%plot
figure
hold on

plot(L(:,1),L(:,2),'r')
plot(xi,yi,'b')
xlabel('x')
ylabel('y')
% Add text 
text(mean(L(:,1)),mean(L(:,2))+0.02,'p(x)','FontSize',20)
text(mean(xi),mean(yi)-0.02,'f(x)','FontSize',20)

You can use the 'XTick' and 'XTickLabel' as specified in,
