Question

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

f(x) = 3 - 2x

(-2, -1)
(-1, 5)
(0, 3)
(1, 0)
(2, -1)

Answer 1

What ones do you think are correct? Just plug them into the equation and see if it is true or no

Answer 2

i have no clue how to do that i mean i no where to put them but i dont no how to see if the answer is correct or not because i do not no how to solve them

Answer 3

f(x) = 3 - 2x

Lets try this point (-2, -1)
-1 = 3 - 2(-2)
-1 = 3 - 2(-2)
-1 = 3 + 4
-1 = 7

Since -1 = 7 it is false and is not a solution.

Answer 4

what?

Answer 5

I took the equation f(x) = 3 - 2x and then I used the point, which is the first point you have (-2, -1) -2 is in the x position and -1 is in the y position. f() = y position and x where you see 2x = x position. take the x and y of the point (-2,-1) and plug it into your equation and solve like I did but do it with the rest of the points.

Answer 6

oh okay
