Select the domain and range of f. f = {(x, y ) | x + y = 10}. domain: {10} range: {10} set f is not a function and does not contain a domain or range domain: all real numbers range: all real numbers

Domain: All Real Numbers

Range: All Real Numbers

Step-by-step explanation:

F is

F = {(x, y ) | x + y = 10}

(x,y) is the ordered pair

x + y = 10  is the expression

We can rearrange it

y = 10 - x

And then we can plot it using a graphing calculator. See attached image

By looking at the plot and examining the expression, we can see that there are no restrictions over x or y.

This means that the domain and range are all real numbers

Domain: All Real Numbers

Range: All Real Numbers

F is a function because it is a relation that associates each element x to a single element y.

i think the answer is b.

not 100% sure though.
