How to determine if an ordered pair is a function or not

👉 Learn how to determine whether relations such as equations, graphs, ordered pairs, mapping and tables represent a function. A function is defined as a rule which assigns an input to a unique output. Hence, one major requirement of a function is that the function yields one and only one result. Thus, equations, graphs, ordered pairs, mappings or tables where any of the input has more than one output does not meet the requirement of a function and hence is not a function. Our process will vary for each type of information given but the idea is the same. Does each input value map, relate, output to one unique y, output value.

which ordered pairs are you speaking of? just plug in the x coordinate in for the x value and the y coordinate for the y value of your equation. If your equation simplifies to be true then your point is on the graph

My question is different. I have four points on a graph. I am being as which one should be removed from the graph so that the graph represent a function. My points are (1, 1) (3, 2) (5, 2) (7, 4) If I look at the x axis I have a 1, 3, 5, & 7. If I look at the y axis I have a 1, 2 on 2, 3, & 4. Any help would be appreciated!

Does the order of ordered pairs matter in writing a Cartesian product of two sets?

[瘋狂是真實的]

Wait so a ordered pair is just rain and range?
