I wanted to understand how does one plot graphs for cubic functions.
for example ,
$y^2 = x^3 + 2x + 10$
Since this is a cubic function , i understand for every x value , y has a reflection along the x axis. Question being how does one compute the y when x is negative. Since you then end up with square root of a negative number. I am not sure what more i can try to solve this.
