Hi I write this code but I don't understand why its not curve..

documentclass[12pt]report
begindocument

beginfigure [H]
begintikzpicture
 draw[-latex] (-2,0) -- (6,0) node[right] $Return%$;
 draw[-latex] (0,-4) -- (0,6) node[above] $Utility$;
draw (-2,-4) .. controls (0,0) and (0,0)..(5,5); 

endtikzpicture
endfigure
enddocument

I need to do this thanks <code>enter image description here</code>

where are the errors??

I'd use three points and to the control points as relative polar coordinates, ++(30:1), then the control points are vectors at the end of the curve segments and by controlling the length and direction you control the curve. Just make sure that the two control points in and out of zero, are on the same line, but opposite directions.

You need to put the line usepackagetikz in your preamble, and change the capital H to a small h in beginfigure[H]. That's what is preventing your current code from compiling!

There's certainly more powerful tools available. Nevertheless, here's a simple approach that renders:

enter image description here

Here's the code:

documentclass[12pt,border=6pt]standalone
usepackagetikz
usetikzlibrarycalc
begindocument
defaeAngleAB80
defaeAngleCD55
defaeANgleEF5

begintikzpicture[%%
 %% control point/.style=inner sep=2pt,circle,draw=red,
 control point/.style=inner sep=2pt,circle,
 primary point/.style=inner sep=2pt,circle,draw=blue,
 ]

 draw[-latex] (-2,0) -- (6,0) node[right] $Return%$;
 draw[-latex] (0,-4) -- (0,6) node[above] $Utility$;

node[primary point] (P1) at (-2,-4) ;
node[primary point] (P2) at (0,0) ;
node[primary point] (P3) at (7,4) ;

node[control point] (C1) at ($(P1)+(aeAngleAB:10pt)$) ;
node[control point] (C2) at ($(P2)+(180+aeAngleCD:40pt)$) ;
node[control point] (C3) at ($(P2)+(aeAngleCD:110pt)$) ;
node[control point] (C4) at ($(P3)+(180+aeANgleEF:60pt)$) ;

%% path[dashed,magenta,draw] (P1) -- (C1) -- (C2) -- (P2) -- (C3) -- (C4) -- (P3);
path[dashed,magenta] (P1) -- (C1) -- (C2) -- (P2) -- (C3) -- (C4) -- (P3);

draw[blue] (P1) .. controls (C1) and (C2) .. (P2);
draw[blue] (P2) .. controls (C3) and (C4) .. (P3);

endtikzpicture

enddocument

Add draw=red to the key control point and add draw to the path[dashed,magenta] to see the interaction between control points and the graph

@Tommaso Dellolmo This is a great suggestion for how to get the result you want, but I just want to stress that your problems were caused by not loading the tikz package and wrong syntax for the figure environment.
