Student Id(main idea)

Question 1                                                                                                                                                       Marks 07

 

Let A= {1, 2, 3} and B= {1, 2, 3, 4},

Define a binary relation R from A to B as follows:    

R= {(a, b) ÎA´B| a>b}

Then

i)                    Find R as a set of ordered pairs.

ii)                  Find domain and range of R.

iii)                Draw the directed graph of R.

Answer:

Let A= {1, 2, 3} and B= {1, 2, 3, 4},

Define a binary relation R from A to B as follows:    

Binary relation:

                    A´B={(1,1)(1,2)(1,3)(1,4)(2,1)(2,2)(2,3)(2,4)(3,1)(3,2)(3,3)(3,4)

                         Find R as a set of ordered pairs.

                             R= {(a, b) ÎA´B| a>b} 

                             Let A= {1, 2, 3} and B= {1, 2, 3, 4},

                            A is always greater in R condition in any A´B  so

i                                                                  {(2,1)(3,1)(3,2)}

                Find domain and range of R.

                Domain:

 the set of first element of the ordered pairs

Dom  R= {(aÎA|(a,b) ÎR } 

Range:

 second element of the ordered pairs denoted to

Ran  R= {(bÎB|(a,b) ÎR } 

i)                    Draw the directed graph of R.

                 

A´B={(1,1)(1,3)((2,1)(2,2)(3,2)(3,3)}

                                        2                                       

Question 2                                                                                                                                               Marks 07

 

Let f: R®R be defined by

         

Determine whether or not f is                                                                                                

a)      one-to-one

b)      onto

 

So   f   is one to one function:

 

               

Question 3                                                                                                                                                 Marks 06

 

Find the 50^th term of the sequence

37, 27, 17, …

a=37

n=50

Using formula

Find the difference

d=27-37

d=-10
