#1) Domain x!=2, Range y!=0 plot(1/(x-2),xmin=1.9,xmax=2.1,ymin=-100,ymax=100) 
       
#2) Domain x>=-1, Range y>=0 plot([sqrt(1+x),-sqrt(1+x)],-1,20,aspect_ratio=1) 
       
#3) Domain -1<=x<=1, Range 0<=y<=1 plot([-sqrt(1-x^2),sqrt(1-x^2)],aspect_ratio=1) 
       
#4) cardinality of the Domain = 900 #4) cardinality of the Range = 27 
       
#5) def h(n): return n*n+1 show(h(1)) show(h(2)) show(h(3)) show(h(4)) show(h(5)) show(h(6))
