Question

Determine the domains and ranges from your relations.
1. R= {(2,1),(2,2),(2,3)}
2.S= {(-2,-4),(-1,1),(0,0),(1,1),(2,4)}

please solve it.. ​

Answer 1

Answer:

domain is for 1st one is 2.2.2

range 1,2,3

and for 2 nd one domain -2, -1, 0,1,2

range 4,1,0,1,4

Answer 2

Answer:

R={(x,x+5):x∈{0,1,2,3,4,5}}

⇒R={(0,5),(1,6),(2,7),(3,8),(4,9),(5,10)}

∴ Domain of R={0,1,2,3,4,5}

Range of R={5,6,7,8,9,10}

R={(x,x+5):x∈{0,1,2,3,4,5}}

⇒R={(0,5),(1,6),(2,7),(3,8),(4,9),(5,10)}

∴ Domain of R={0,1,2,3,4,5}

Range of R={5,6,7,8,9,10}
