Question

what is the output value of the given function when the input value is 3?
y = 4x - 5
(3, ?)

Explanation:

Step1: Identify the input value

The input value \( x \) is given as 3.

Step2: Substitute \( x = 3 \) into the function

We have the function \( y = 4x - 5 \). Substitute \( x = 3 \) into it:

$$ y = 4(3) - 5 $$

Step3: Calculate the result

First, calculate \( 4(3) = 12 \). Then subtract 5 from 12:

$$ y = 12 - 5 = 7 $$

Answer:
