What is a Boolean function?

Answer: A Boolean function is a function that operates on one or more binary variables (0 or 1) and returns a binary value (0 or 1), dealing with truth values, i.e., true (1) or false (0). Three examples of Boolean functions are: 1. NOT operation: It inverts the input (e.g., turning 1 to 0, or 0 to 1), represented as \(NOT(x) = \bar{x}\) where x is a binary input. 2. AND operation: It returns true (1) only if both inputs are true (1); otherwise, it returns false (0), represented as \(AND(x, y) = x \cdot y\) where x and y are binary inputs. 3. OR operation: It returns true (1) when at least one of the inputs is true (1); otherwise, it returns false (0), represented as \(OR(x, y) = x + y\) where x and y are binary inputs.
