Define a relation

*R*from**R**to**R**as follows: For all (*x,y*) ∈**R**×**R**,(*x,y*) ∈*R*if and only if,*x*=*y*^{2}+ 1*.*Write three sets of ordered pairs that are in*R*. Write the domain and co-domain of*R*. Is*R*a function from*A*to*B*? Explain.
three sets of ordered pairs that are in R:
{(1,2),(2,5)

Define a relation *R* from **R** to **R** as follows: Restraint full (*x,y*) ∈ **R** × **R**,(*x,y*) ∈ *R* if and merely if, *x* = *y*^{2} + 1*.*

Write three fixeds of ordered pairs that are in *R*.

Write the territory and co-territory of *R*.

Is *R* a office from *A* to *B*? Explain.

three fixeds of ordered pairs that are in R:

{(1,2),(2,5),(3,10),(4,17)}

Is R a office from A to B?

Yes, R is a office owing restraint incessantly atom in A there is merely individual likeness in B.

Write the territory and coterritory of R.

Territory is any developed calculate restraint the fixed R

Coterritory is merely dogmatic developed calculates from the fixed R
