Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Cube Root Function
The cube root function, denoted as f(x) = ∛x, is a type of radical function that returns the number which, when cubed, gives the input x. This function is defined for all real numbers and has a characteristic S-shaped curve that passes through the origin (0,0). Understanding its basic shape and properties is essential for applying transformations.

Graph Transformations
Graph transformations involve shifting, reflecting, stretching, or compressing the graph of a function. In this case, the transformation involves a vertical reflection and a horizontal shift. Specifically, the function -∛(x+2) reflects the cube root function across the x-axis and shifts it left by 2 units, altering its position and orientation.

Intro to Transformations
Function Notation and Evaluation
Function notation, such as f(x), represents a relationship between input values (x) and output values (f(x)). Evaluating a function involves substituting specific x-values into the function to find corresponding outputs. Understanding how to manipulate and evaluate functions is crucial for accurately graphing transformed functions and interpreting their behavior.
