Question

11. Find the Domain and Range of the following: (6.-1) (-2.2) (18,-1) (-2,3) Domain: Range: Is this relation a function?​

Answer 1

Note:-

• Domain is the input.
• Range is the output.
• If an relation be (x,y) then x is the domain ,y is the range .

Solution:-

$\\ \sf\longmapsto D_f=\{6,-2,18\}$

$\\ \sf\longmapsto R_f=\{-1,2,3\}$

No it's a relation not function

Answer 2

Answer:

solution,

R={(6,-1),(-2,2),(18,-1),(-2,3)}

domain={6,-2,18}

range={-1,2,3}

domain:range is the relation a function…
