There are an infinite number of functions that could take that one example input and give that output.

Hi Here the solution:
% Your cloud point
x=[1,3,8,25,45,23];
y=[25,24,13,69,25,75];
% calculate a new cloud point that contain the last one
xnew = [1, 1.5 ,3,6,8,25,32,45,31,23];
ynew = interp1( x,y, xnew,'pchip' );
% plot de new values
plot(x,y,'o');hold on;plot( xnew, ynew,'r' )
% polinomios
p = interp1( x,y,'pchip' );

You can define x values in ascending order with sort.
Then you can order de y values.
[xtointerpol indx ] = sort(x);
ytointerpol = y(indx);
