Let g be the relation on the sot Nol natural numbors defined by xRy f and only y tivides y Then gis Question 11 The function F delined by the formula f(x) - V5-x + x-3 has domain then interval [3,5) Question 12 Let f(x) = x + 1 and g(x) = x then (fo g)(x) - Question 13 Let = ((2,4), (3,4), (3,1), (5,5) then Dom()- (1,4,5) Question 14 Let be the relation from A = (1,2,3) to 8 = (1,2,3,4,5,6) given by = ((3,1). (2,3), (1,6), (2,6), (3,5), (1,2), (2,2)). Than Dom() = A =(1,2,3} and Rng(9) = (1,2,3,5,6) Question 15 then (x) Let f:R - Rba defined by f) =
