Question

what is the value of the function $y = 3x - 1$ when $x = -1$?

-8

-4

2

6

Explanation:

Step1: Substitute \( x = -1 \) into the function

We have the function \( y = 3x - 1 \). Replace \( x \) with \( -1 \), so we get \( y = 3(-1) - 1 \).

Step2: Calculate the value

First, calculate \( 3(-1) = -3 \). Then, subtract 1: \( y = -3 - 1 = -4 \).

Answer:

\(-4\) (corresponding to the option with \(-4\))
