pls can somebody help me...

Answer:
Domain and Range in set notation
Domain: {x|x=4,0,-2}
Range: {x|x=-1,4,9,-9}
Step-by-step explanation:
We are given a relation G
G={(4,-1),(0,4),(-2,9),(-2,-9)}
We need to find domain and range of the relation G
Domain: The domain is the set of all first elements of ordered pairs (x-coordinates)
Range: The range is the set of all second elements of ordered pairs (y-coordinates).
So for the given relation G={(4,-1),(0,4),(-2,9),(-2,-9)}
Domain is: (4,0,-2)
Range is: (-1,4,9,-9)
So, Now writing Domain and Range in set notation
Domain: {x|x=4,0,-2}
Range: {x|x=-1,4,9,-9}
