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 is all Real Numbers and the Range is all Real Numbers.

Step-by-step explanation:

It is a function.

The graph of this function is a straight line passing  through the x axis at (10,0) and the y-axis at  (0,10). The line  continues to the left and right without bounds.

So the Domain is all Real Numbers and the Range is all Real Numbers.
