Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Function Notation
Function notation, such as ƒ(x), represents a mathematical relationship where each input x corresponds to exactly one output. Understanding this notation is crucial for evaluating functions, as it indicates how to compute the output based on the given input value.

Interval Notation
Greatest Integer Function
The notation [[x]] typically denotes the greatest integer function, also known as the floor function. This function rounds down a real number x to the nearest integer less than or equal to x. For example, [[3.7]] equals 3, while [[-2.3]] equals -3.
