Question

Write the relation as a set of ordered pairs.

a. ordered pairs: {(4, –2), (0, 0), (2, 4)}
b. ordered pairs: {(–2, 4), (0, 0), (4, 2)}
c. ordered pairs: {(–2, 4), (0, 0), (2, 4)}
d. ordered pairs: {(4, –2), (0, 0), (4, 2)}

Answer 1

Set of ordered pairs is
(-2, 4), (0,0 ), (2, 4).

On the first place is the number where arrow begins, on the second place is the number where the arrow ends.

c. ordered pairs: {(–2, 4), (0, 0), (2, 4)}

Answer 2

c. ordered pairs: {(–2, 4), (0, 0), (2, 4)}

Explanation:

It's important to remember that, the first the showed in the image represents a domain, and the second set represents a range. That means the values -2, 0, 2, must appear as the first value in the coordinate, and the values 4 and 0, must appear second.

Now, if we associate the given diagram as coordinates, it would be like

`(-2,4),(0,0),(2,4)`

Thereofre, the right answer is choice c.

Additionally, this relation models a quadratic function actually, because -2 and 2 has the same image 4.
