#1) Graph y^2==12*x var('y') solve(y^2==12*x,y)
plot([-sqrt(12*x),sqrt(12*x)],0,3,aspect_ratio=1)
#2) Graph y^2==-8*x solve(y^2==-8*x,y)
plot([-sqrt(-8*x),sqrt(-8*x)],-2,0,aspect_ratio=1)
#3) Graph x^2==-12*y solve(x^2==-12*y,y)
plot([-x^2/12],-6,6,aspect_ratio=1)
#4) Graph (y-3)^2==8*(x+3) solve((y-3)^2==8*(x+3),y)
plot([3+sqrt(8*x+24),3-sqrt(8*x+24)],-3,1,aspect_ratio=1)
#5) Graph x^2+4*x-4*y==0 solve(x^2+4*x-4*y==0,y)
plot([x^2/4+x],-4,0,aspect_ratio=1)
