Answer 1

Answer:

f(-2.75)=-1

Step-by-step explanation:

Here we are given a Greatest Integer Function . The characteristic of this function is that it when operated , gives you the greatest integer it has near to it.

Hence if we have any greatest integer function f(x)=[x] , for x = -2.75

[-2.75]=-2 , as -the greatest integer near to -2.75 is -2 as -3<-2

Now coming back to our problem, our function is

f(x)=[x]+1

Hence for x=-2.75

f(x)=[-2.75]+1

as we discussed above [-2.75]=-2

Hence

f(-2.75)=-2+1

f(-2.75)=-1
