Question

For the following table, write a rule for f using the ceiling or floor function

  1. Ceiling (x) + 4 , 0 < x ≤ 6
  2. Ceiling (x) + 5 , x > 0 
  3. Ceiling (x) – 4 , 0 ≤ x ≤ 6
  4. Ceiling (x) + 1 , x > 0 

Hint:

The ceiling function returns the smallest nearest integer which is greater than or equal to the specified number.
 The floor function returns the largest nearest integer which is less than or equal to a specified value.

The correct answer is: Ceiling (x) + 4 , 0 < x ≤ 6


    The function can be f(x) = ceiling (x) + 4, 0 <x ≤ 6
    Recheck by putting the values of x from the table in the above equation.

    Know the difference between floor and ceil in order to solve the problem.
