Math Problem Statement

Find the indicated functional value for the floor function: f(−0.75) ?

Solution

To find the indicated functional value for the floor function f(x)f(x) at x=0.75x = -0.75, we use the definition of the floor function. The floor function, denoted as x\lfloor x \rfloor, returns the greatest integer less than or equal to xx.

Given x=0.75x = -0.75:

0.75\lfloor -0.75 \rfloor

The greatest integer less than or equal to 0.75-0.75 is 1-1.

Thus,

0.75=1\lfloor -0.75 \rfloor = -1

So, the functional value f(0.75)=1f(-0.75) = -1.
