## anonymous one year ago 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)

1. anonymous

The points are in the format : $$(x, f(x))$$, so first value is $$x$$ and other value is $$f(x)$$..

2. anonymous

One by one, put $$x$$ and $$f(x)$$value from the options in the expression given to you, and check whether you get the equation satisfied or not..

3. anonymous

Like I try your first option: There $$x = -2$$ and $$f(x) = -1$$, put these values in the expression given: $-1 = 3- 2(-2) \\ -1 = 3 + 4 \\ -1 \ne 7$

4. anonymous

so three and five are correct?

5. anonymous

So, option 1 is not satisfying the equation..

6. anonymous

Yes, Excellent...
