The first number in an ordered pair is the x-coordinate and the second number is the y-coordinate. The dot we draw to represent the ordered pair is called a point. To set our minds at ease, we'll assume for the time being that this process is of more value when dealing with functions than when dealing...By definition, a function is a relation where each input has exactly one output. In letter A, the inputs 0, 1, 2, and 3 all have exactly one output. In B, the input 1 has two outputs.The graph represents a function because each domain value (x-value) is paired with exactly one range value (y-value). You can sometimes identify a linear function by looking at a table or a list of ordered pairs. Tell whether each set of ordered pairs satisfies a linear function.Home» Questions »Science/Math » Math » Calculus » Which sets of ordered pairs represent functions... narrowed it down to either B or C, but I'm not sure because they both don't use a letter or number twice as x. So I'm not sure which one is a function.Type: Multiple-Choice Category: Functions and Relations Level: Grade 8 Standards: 8.F.A.1 Author: Sammielyn Last Modified: 2 years ago.

Which set of ordered pairs represents a function? - Brainly.com
I know that this is easy, and I know how to determine whether something is a function or just a set of ordered pairs but anyway...14) Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.)Learn to determine if a relation given by a set of ordered pairs is a function.In mathematics, an ordered pair (a, b) is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair (a, b) is different from the ordered pair (b, a) unless a = b...

Since a function is a set of ordered pairs where there is only one value of y. Therefore, a graph will represent a function if the vertical line test passes. In other words, no vertical line intersects the graph more than once.Any set of ordered pairs? Then [math]\{(0,0),\ (0,1)\}[/math] does not define (the graph of) a function. Why? The idea of a function is that every input (domain element) should have a unique output (codomain element). Here we "partner up" [math]0...The second set represents a function. The first, third and fourth sets do not represent functions.Any set of ordered pairs may be used in a relation. No special rules are available to form a relation. A function is a set of ordered pairs in which each x-element has Only One y-element associated with it. Examine the three sets of relations given to determine if any of them strictly follows the rule for...Which set of ordered pairs represents a function? Which explains why the graph is not a function? It is not a function because there are two different y-values for a single x-value.
#" "#Given: Three Sets of Relations, say #color(purple)(A, B,)# and #color(crimson)(C.#
Definition of a Relation:
A relation is solely a set of enter and output values, represented in ordered pairs.
Any set of ordered pairs may be utilized in a relation.
No particular rules are to be had to shape a relation.
Definition of a Function:
A function is a set of ordered pairs in which each and every x-element has Only One y-element related to it.
Examine the three units of relations given to decide if any of them strictly follows the rule for being a function.
#colour(inexperienced)("Step 1")#
Set the Input knowledge table up:
#color(inexperienced)("Step 2")#
Rewrite the knowledge desk to facilitate comparing #color(purple)(x# values of each set:
A simple visible exam tells us that #color(red)("Set C"# has #color(blue)(x = -2# twice.
Note that #colour(red)("Set B"# uses the value #color(blue)((-5)# two times for the y-coordinate.
But, x-coordinate values are NOT repeated.
Set B is a function using the rule of thumb.
Hence,
#color(blue)("Set C"#does NOT constitute a function.
#colour(green)("Step 3")#
Plot ordered pairs of #colour(blue)("Set A"# on a Cartesian coordinate airplane:
#color(inexperienced)("Step 4")#
Plot ordered pairs of #color(blue)("Set B"# on a Cartesian coordinate aircraft:
#color(green)("Step 5")#
Plot ordered pairs of #color(blue)("Set C"# on a Cartesian coordinate plane:
#colour(red)(C_1(-2,1), C_3(-2,-6)# have the similar x-coordinate value.
Hope it is helping.
