Answer 2

Answer:

The value of [-12] is -12          

Step-by-step explanation:

Given the greatest integer function with the value -12

we have to find the value of  [-12]

By the definition of greatest integer function

The greatest integer function is a function which is  piece-wise defined.

If the number given under the greatest integer function is an integer, we take same value of function which is integer. If the number is not an integer, we use the next smaller integer i.e

The value of x is x i.e [x]=x: if x is integer

The value of x is x-1 i.e [x]=x-1: if x is not an integer

Given [-12]

As -12 is integer therefore the value of

[-12]=-12
