Question

IfR={(x,y):x,y∈N,x2 +y2=100},WriteRinrosterform. Also find the domain and range.

Answer 1

Answer:

We have 3

2

+4

2

=25 or, 4

2

+3

2

=25 and 0

2

+(5)

2

=25 or, 5

2

+0

=25.

So the domain of R is {0,3,4,5}. [ Values corresponding to x for x being whole number]

And the range is {0,3,4,5}. [ Values corresponding to y for y being whole number]
