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

Determine if the relation represents y as a function of x. If it is a function, identify-example-1
