Question

Find the value of f(x) = [2.7] a. 2 b. 2.7 c. 3

Answer 1

The correct answer is A.

EXPLANATION

The given function is called the greatest integer function.

That is

f(x)=[x]

f(2.7)=[2.7]=2

The input is 2.7, the output

is the greatest integer that is less than or equal to 2.7

All integers less than 2.7 are

$,...,-3,-2,-1,0,1,2}.$

The greatest of all of them is 2.

In programming... The int variable behaves like this function.

int(2.7) will give you 2

Simply put that function gives you the integer part of whatever is in it.
