Which interval notation represents the set of all numbers greater than or equal to -11and less than or equal to 5?a) (-11,5) b) (-11,5]c) [-11.5)d) [-11,5]

Respuesta :

the interval notation is [-11, 5]. Option D

First let's represent the question with inequality.

let the set of number represent x

x is greater than or equal to -11:

[tex]x\ge-11[/tex]

x is less than or equal to 5:

[tex]x\leq5[/tex]

This means the interval notation is between -11 and 5.

[tex]-11\leq x\leq5[/tex]

In interval notation, you start with [ and end with a bracket

Hence the interval notation is [-11, 5]. Option D.
