An ordered pair is the output (y) value of the relation the input (x) value of the relation a set of points that pair input values with output values x and y values written in the form (x, y) will give medal
Im sure you know the typical ordered pair we encounter commonly, i.e. x-y coordinates on a graph. So you can probably eliminate two of these choices immediately.
Now think of where these values come from. You probably use functions quite often. How are these usually written? f(x)=y. How would you describe x and y?
is it the last one
Nope. Consider the function. Your teacher might have described it this way: given a function: you put something into it (x), and get something else out (y).
im homeschooled
Well, think of a function as a machine, you drop something into it, and it spits out something else. If I give you a function like f(x)=2x, this is saying that, for any x, it spits out twice that x.
another way of writing a function is y=2x
so it is c.
so its not one of the first ones
thanks
it's not C, it's actually x and y values written in the form (x, y) one way to remember this is that x and y are thought together as a pair
since order matters, (x,y) is NOT the same as (y,x) and x must come first, it's ordered so that's where the term "ordered pair" comes from
