Question

Select all of the following that are ordered pairs of the given function.

Answer 1

If you plug x-coordinate in x then solve for y, and what you get for y matches t-coordinate, then this is correct ordered pair.

For explain: (-2, -1)

Plug in x-coordinate; f(-2) = 3 - 2(-2) = 3+4 = 7

-1 isn't equals to 7, so (-2, -1) is not right order pair.

Doing that thing and you should get:

Answer: (-1, 5), (0, 3), (2, -1)

Answer 2

These are the answers

(-1,5)

(0,3)

(2,-1)
