Solution

## The correct option is C Domain is {2,5,8,23}If the function is given as collection of ordered pairs (x,y), then domain of the function is " All the values of x" and range of the function is " All the values of y" Here we know the function is f={(2,3),(5,7),(8,15),(23,29)} so values of x are 2,5,8 and 23 and values of y are 3,7,15 and 29. Hence, Domain of the function is {2,5,8,23} And Range of the function is {3,7,15,29}.
