c

Let f be a function from A to B, then f is bijective function if it is both one-one and……
a) into    
b) onto                   
c) injective           

b

If C={1,2, 3} and D={a, b, c,d} and 
f={(1,a),(2,b),(3, c)} then function is called
a) onto   
b) one-one             
c) injective           

b

If C={1,2,3,4} and D={a ,b ,c ,d} and 
f={(1,a),(2,b), (3,c), (4,d)} then function is called……….
