Think of the x and y as questions and answers. If you repeat a question you should get the same answer. If you don't then it is not a function.

(2,3),(2,4) is not a function.

Why is the order of the base pairs along a gene important?

The base pairs are ordered such that they spell out the order in which amino acids will be placed to build a protein. When they are in the wrong order, either the wrong amino acid is made, or sometime it will create a shortened protein which may or may not perform its intended function.


Is the order of base pairs from top to bottom different or the same for each new DNA model?

The order of base pairs from top to bottom is the same for each new DNA model. In a DNA molecule, adenine pairs with thymine and cytosine pairs with guanine, forming a consistent sequence. This pairing is fundamental to the structure and function of DNA.


If a set of ordered pairs is not a relation can the set still be a function?

If a set of ordered pairs is not a relation, the set can still be a function.


How you tell if set of ordered pairs a function?

If there are any pairs with the same second element but different first elements, then it is not a function. Otherwise it is.


How does graphing the order pairs of a relation can help decide if the relation is a function?

If a relation can be called a function, it means that the relation maps every element to one and only one other element. If you have some ordered pairs and see that, for example, 1 maps to 4 (1,4) and 1 also maps to 7 (1,7) , you don't have a function.


What is a function table?

a function table is a table used to find number pairs


When do factors pairs of 100 go In reverse order?

There is no order to factor pairs: you can present them in any order that you like.


What is the function in algebra of ordered pairs?

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.


Would it be easier to find the rule for a function table with 3 pairs of numbers or 4 pairs of numbers?

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.


Which pairs of ordered pair could you remove from the relation -1013222331 so that it become a function?

To determine which pairs of ordered pairs can be removed from the relation -1013222331 to make it a function, we need to identify any duplicate first elements. A relation is a function if each input (first element) is associated with exactly one output (second element). If there are any pairs with the same first element but different second elements, one of those pairs must be removed to ensure the relation meets the definition of a function.


How do you write ordered pairs from a function table?

The function table will have two columns, one for the x-value and one for the y-value. Form ordered pairs (x,y) by inserting the values from one row of the table.


Which pair share the same function?

To accurately answer your question about which pair shares the same function, I would need specific options or pairs to consider. Please provide the pairs you are referring to, and I will be happy to help!
