Given: A graph
Required: Determine if the relation represents y as a function of x. If it is a function, identify the domain and range.
Explanation:
It is a function, since every x belongs to a unique y.
From the graph, domain is values of x.
x takes all the values greater than -4.
So domain is x> -4.
Range is values taken by y.
y takes all the values greater than -4.35 (it starts from -2, goes up. then comes downwards to -4.35 and then goes up to infinity).
So range is y > -4.35
Final Answer: It is a function with domain x>-4 and range y>-4.35
