Math Problem Statement

can you describe the set  N={x |x is an integer and -5<x<-1}

Solution

The set N={xx is an integer and 5<x<1}N = \{ x \mid x \text{ is an integer and } -5 < x < -1 \} represents all integers that satisfy the condition that xx is greater than 5-5 and less than 1-1.

The integers between 5-5 and 1-1 (exclusive) are: N={4,3,2}N = \{ -4, -3, -2 \}

So, the set NN contains the integers 4,3,-4, -3, and 2-2.

Would you like more details or have any questions?

Related Questions:

  1. How would the set change if the inequality was 5x1-5 \leq x \leq -1?
  2. What would the set look like if it included all real numbers instead of just integers?
  3. How can you represent this set on a number line?
  4. What would the set look like if xx had to be a positive integer?
  5. How can this set be expressed in interval notation?

Tip: When working with sets defined by inequalities, always check whether the boundaries are included (i.e., whether the inequality is strict or not).
