Question 184095
<font face="Times New Roman" size="+2">


Both ends of your interval have square brackets, so both of your inequality signs must include equals:


*[tex \LARGE \text{          }\math -1 \leq x \leq 4]


Compare this with (-1,4], [-1, 4), and (-1,4) whose descriptive inequalities are, respectively:


*[tex \LARGE \text{          }\math -1 < x \leq 4]


*[tex \LARGE \text{          }\math -1 \leq x < 4], and


*[tex \LARGE \text{          }\math -1 < x < 4]
