If it's a linear function, 3 should do, but 4 will give an extra check on you work.
If the function is quadratic exponential, etc. then at least 4 pairs should be used.
A relation has pairs of numbers. A function is a special relation where for each input there is one and only one output.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
y = 2x + 3 is a function rule. This rule can also be written in several different ways:f(x) = 2x + 3 "f of x equals ...', or f: x -> 2x+3 "f maps x as ...".As a set of ordered pairs. Here is a set of pairs which satisfy our function, f: {(1,5), (2,7), (3, 9), (4, 11)}.A table of values, also known as a 'T chart'.A mapping diagram,, which has two oval shapes with numbers in them, and arrows joining the numbers in one oval to the numbers in the other oval.
80 has 5 factor pairs.
There are two pairs of even numbers that satisfy the condition. They are (8, 10) and (6, 12).
If one x-value does not have two y-values, then it is a function. In other words, x cannot be repeated. For example, take a parabola whose vertex is at the origin and points are all found in the first and fourth quadrants, forming a "c" of sorts. This graph would not pass the vertical-line test and would therefore not be considered a function.

The function in algebra of ordered pairs is function notation. For example, it would be written out like: f(x)=3x/4 if you wanted to know three fourths of a number.
If there are n numbers in the group, there aren2 ordered pairs if the numbers can be repeated,n*(n-1) ordered pairs if the numbers cannot be repeated,n2/2 pairs if the numbers can be repeated,n*(n-1)/2 pairs if the numbers cannot be repeated.
There are an infinite number of possible answers. One of the easier pairs is 1 and 31.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
I'd hate to give you a definition like, "Related pairs of numbers are pairs of numbers that are related" so let's just go with an example. Let the first number of a pair represent a quantity of bicycles. Let the second number represent the number of tires per bicycle. With 1 bicycle you would have 2 tires, with 2 you would have 4 and so on. (1,2)(2,4)(3,6)(4,8) are related pairs of numbers.

If a set of ordered pairs is not a relation, the set can still be a function.
Adding consecutive pairs of numbers will always turn out to be an odd number. It would have to be consecutive odd numbers: 45 and 47.
If there are any pairs with the same second element but different first elements, then it is not a function. Otherwise it is.
