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

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

Answer 2

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..

Answer 3

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

Answer 4

so three and five are correct?

Answer 5

So, option 1 is not satisfying the equation..

Answer 6

Yes, Excellent...

Answer 7
