Write the solution set in interval notation. Select the correct choice below and, if necessary, fill
A. The solution set is $\square$
B. The solution set is $\varnothing$.
Solution
Solution Steps
Step 1: Analyze the inequalities
We are given two inequalities: $x < 1$ and $x > -1$. We are looking for values of $x$ that satisfy both inequalities simultaneously.
Step 2: Visualize on the number line
The inequality $x < 1$ represents all numbers less than 1. The inequality $x > -1$ represents all numbers greater than -1. The solution set will be the overlapping region where both inequalities are true. This is the region between -1 and 1, excluding -1 and 1.
Step 3: Write the solution in interval notation
The solution set in interval notation is $(-1, 1)$. This means all numbers between -1 and 1, excluding -1 and 1. The graph would be an open circle at -1 and an open circle at 1, with the line shaded between them, corresponding to graph C.
Final Answer
The correct graph is C. The solution set in interval notation is $(-1, 1)$.
