Question

Select the domain and range of F. F = (x, y ) . 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

Answer 1

Domain: All Real Numbers

Range: All Real Numbers

Explanation:

F is

F = 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.
