Question

If R = {(x,y) : y = 2x+7, where x belongs to Z, -5 less than or
equal to x less than or equal to 5} is a relation

R=x,y:y=2x+7,where x∈Z , -5≤x≤5So, x∈-5,-4,-3,-2,-1,0,1,2,3,4,5R=-5,-3,-4,-1,-3,1,-2,3,-1,5,0,7,1,9,2,11,3,13,4,15,5,17So, domain is -5,-4,-3,-2,-1,0,1,2,3,4,5AndRange is -3,-1,1,3,5,7,9,11,13,15,17
