Question

is the function? {(x,y): y^2 = x ,x,y€R}​

Answer 1

Answer:

Step-by-step explanation:Given R={(x,y):x,y∈W,x2+y2=25}, where W is the set of all whole numbers. Find the domain and range of R.

Easy

Answer

We have 32+42=25 or, 42+32=25 and 02+(5)2=25 or, 52+02=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]
