Question

Which of the following values would complete the ordered pair if the point is on the graph of ƒ(x) = -2x - 1? (-2, ___)

Answer 1

Answer:

A

Step-by-step explanation:

(x coodinate, y coodinate) = (x, f(x))

(-2, ___) is saying us x=-2, and question is asking y =?

f(x) = -2x -1

f(-2) = -2.-2 -1

f(-2)= 4 -1

f(-2) = 3

so, y= f(-2) = 2

(x, f(x)) = (-2, f(-2)) = (-2,3)

Hope this helps ^-^

Answer 2

Option A: 3 is the right answer

Step-by-step explanation:

Given

$f(x) = -2x-1$

In an ordered pair, the x-coordinate is the input to the function and y-coordinate is the output of the function on specified input.

In the given ordered pair,

x-coordinate is -2 so we will put it into the function to get the y-coordinate

So,

$f(-2) = -2(-2)-1\\= 4-1\\=3$

3 will complete the ordered pair of the point on the graph

Hence,

Option A: 3 is the right answer
