Answer:

C) -3 < x < 1

Explanation:

Given the absolute inequality:


3|x+1|-2<4

First, add 2 to both sides of the equation:


\begin{gathered} 3|x+1|-2+2<4+2 \\ 3\lvert x+1\rvert\lt6 \end{gathered}

Next, divide both sides by 3:


\begin{gathered} (3|x+1|)/(3)<(6)/(3) \\ |x+1|<2 \end{gathered}

We then solve the absolute inequality:

[tex]\begin{gathered} -2The solution to the absolute inequality is -3Option C is correct.
