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

real resolution, x_left, x_right, g_x_left, g_x_right, y_down, y_up;
resolution = 0.001;
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){ // equation to graph
	if (x!=0) { // check for impossible case
    	return 1/x;
	}
    else{
		return y_up+1;
	}
}

void dotgraph(){
	bool prev = false;
	for (real i = g_x_left; i<=g_x_right; i+= resolution){
          if (f(i)<y_up && f(i) > y_down){
                if (prev == true){
                    draw((i, f(i))--(i-resolution, f(i-resolution)), graph_pen);
                }
                prev = true;
          }
          else{
              prev = false;
          }
