So basically, I was bored one day, and I wanted to do some stuff so I went to Desmos. I got bored again, so I thought to make Desmos in asymptote. This is what I got

The code is <syntaxhighlight lang="Asymptote" line>

real resolution, x_left, x_right, g_x_left, g_x_right, y_down, y_up; resolution = 0.01; x_left = -8; x_right = 8; y_down = -8; y_up = 8; g_x_left = -8; g_x_right = 8; pen gray_pen = gray(.7); pen graph_pen = 1+blue; void grid(){ real[] arrx, arry;

   for (real i = x_left+1; i < x_right; i+=1){
   	draw((i, y_down)--(i, y_up), gray_pen);
   }
   for (real i = y_down+1; i < y_up; i+=1){
   	draw((x_left, i)--(x_right, i), gray_pen);
   }
   draw((x_left, 0)--(x_right, 0),Arrows);

draw((0,y_down)--(0, y_up),Arrows);

}

real f(real x){

   return x^2+4x/2;

}

void dotgraph(){ bool prev = false; for (real i = g_x_left; i<=g_x_right; i+= resolution){

  		if (f(i)<8){
           if (prev == true){

draw((i, f(i))--(i-resolution, f(i-resolution)), graph_pen);

           }
           prev = true;
       }

else{

       	prev = false;
       }

} }

grid(); dotgraph(); <syntaxhighlight lang="Asymptote" line>
