Which graph is defined by the function f(x) = x if 0 ≤ x ≤ 4 (where x is the greatest integer function, i. e., the greatest integer less than or equal to x)?

The correct option is 3.

Step-by-step explanation:

The given function is

    if 0 ≤ x ≤ 4

where x is the greatest integer function.

This function can be written as

It means the values of the function is 0 in the interval 0≤x<1, 0 in the interval 0≤x<1, 1 in the interval 1≤x<2, 2 in the interval 2≤x<3, 3 in the interval 3≤x<4, 4 at x=4.

From these interval in is clear that the closed circle in on the left side of the floor and open circle on the right side on each floor.

Therefore the correct option is 3.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

each side has a different length.
