One-One:A functioN F:A to B is said to be one -one function or injuction A into B if different elements in A have different Fimages in B
Ex:A={1,2,3} B={p,q,r,s}
F={(1,r),(2,p),(3,s)}
Onto: a function F:A to Bis said to be onto or surjection from A onto B if F:A=B
Ex:A={1,2,3} B={p,q}
F={(1,q),(2,p),(3,q)}
Into:F:AtoB is a function suchthat it exists at least one element in B which is not the F image of any elementof A then it is knowwn as Into Function
Many to One:If F:A to B is a function if distinct element in Ahave same F image inB then the function is called Many to One
I am sorry if any thing is wrong
