The ordered pair that represents a function is:
⇒ (-3, 3), (-2, -2), (1, 1), (2, -2)
<u>What are Coordinates?</u>
A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines are called the coordinates.
The given points are;
(-3, 3), (-3, -3), (-1, 1), (1, 4)
(-3, 3), (-2, -2), (1, 1), (2, -2)
(-3, 3), (-3, -3), (1, -4), (1, 1)
(-4, 4), (-4, 1), (-2, 1), (2, 1)
Now, For an ordered pair to be a function, either of the following must be true:
Each x-value has exactly one corresponding y-value.
More than one x-values have the same corresponding y-values.
And, If any of the following conditions is true, then the ordered pair is not a function,
One x-value has multiple corresponding y-values.
More than one x-values have multiple corresponding y-values.
From the given options, only ordered pair (-3, 3), (-2, -2), (1, 1), (2, -2) satisfies the condition to be a function.
Because none of its x-values have multiple corresponding y-values.
And, Other ordered pairs are either one-to-many or many-to-many.
So, The ordered pair that represents a function is:
⇒ (-3, 3), (-2, -2), (1, 1), (2, -2)
