(1, –1), (16, –4), (36, –6)
given that the function is
this can also be written as
we have to graph this function and check which list of points lie on the graph
see attachment for graph:
we find that the points lying are (1,-1) (16,-4) and (36,-6)
since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
