Question

What is the domain of the relation graphed below?

Answer 1

Answer:

{-5, -4, -3, 1, 2, 5}

Step-by-step explanation:

The domain of a function is defined as: the set of possible values of the independent value. This means, all the possible values that x can take. The independent value in a graph is represented in the x-axis.

So, in this graph, the values taken by x are -5, -4, -3, 1, 2 and 5.

We can see that there are no other values taken by x (the independent variable)

Therefore, the domain of the graphic is {-5, -4, -3, 1, 2, 5}

Answer 2

Since the only places where an x-ordinate exist are the closed circles, the domain will simply be:

D: { -5, -4, -3, 1, 2, 5 }
