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.

3/6   and 9/18

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
