Explanation / Answer
4 ans is (b) since look 8 has two values so fn is not well defined
5 ans is (d) since f(-2)=-16<23=g(-2)
6 ans is (b)
7 ans is (a) since take a projection on x and y axis resp u get domain and range
8 ans is (d) since square root funtion is defined on positive values
9 ans is c
