Graphing

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

[asy] /** * Graphing Remastered * * Made by tigerbw **/  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(); [/asy]
