Does this table represent a function ? why or why not ?

Step-by-step explanation:

There is only one answer. It is the very definition of what a function is.

The answer is A. That is exactly how a function is defined.

You can have minus numbers and still have a function. B is incorrect.

A function should have different x values. If the sample doesn't have different x values but different y values, you don't have a function C is wrong.

D is wrong. You can have a function if all the y values are different. The x values normally should be as well.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
