Question

Let R be a relation in N defined by
R = {(x, y): x + 2y = 8). The range of R is
(b) {1, 2, 3}
(a) 2 463​

Answer 1

Answer:

The correct answer is Range:{1,2,3}.

Step-by-step explanation:

6+2×1=8→(x,y)=(6,1)

4+2×2=8→(x,y)=(4,2)

2+2×3=8→(x,y)=(2,3)

R={(6,1),((4,2),(2,3)}

Range of any relation consists consists of values of y only.

range={1,2,3}.
