Question

A function has the rule y = -2 x + 11. Which of the following ordered pairs represents an input of 4 and its output? (4, 3.5) (4, 3) (3.5, 4) (3, 4)

Answer 1

Explanation:

`x` is considered the input. We plug it into the function to calculate the value of y...the output.

When we input
`x=4` we get

`y=-2*4+11=3`

So the solution is (4, 3)

Answer 2

(4, 3)

Explanation:

To determine which ordered pair represents an input of 4 and its output for the given function, we need to substitute the value of 4 into the function and check which option satisfies the equation.

The given function is y = -2x + 11.

Substituting x = 4 into the function, we get:

y = -2(4) + 11

y = -8 + 11

y = 3

Therefore, the ordered pair that represents an input of 4 and its output is (4, 3).

Among the given options, (4, 3) is the correct answer.
