Question

Once again, let A = R (the set of real numbers) and B = Z. Let f: A → B be the function that takes a real number a as its input and outputs the least integer that is greater than or equal to a. This function is denoted by f(a) = a and is called the

A) Floor function
B) Ceiling function
C) Identity function
D) Exponential function

Answer 1

The answer to the question is the Ceiling function.

Step-by-step explanation:

The function described in the question is the Ceiling function.

The Ceiling function takes a real number as input and outputs the least integer that is greater than or equal to the input.

For example, if we have f(3.2), the Ceiling function would output 4.
