Here are the essential concepts you must grasp in order to answer the question correctly.
One-to-One Functions
A one-to-one function is a type of function where each output value is uniquely paired with one input value. This means that no two different inputs produce the same output. This property is essential for a function to have an inverse, as the inverse must also be a function, which requires that each output corresponds to exactly one input.

Inverse Functions
An inverse function essentially reverses the effect of the original function. If a function f takes an input x and produces an output y, the inverse function f⁻¹ takes y and returns x. Graphically, the inverse of a function can be found by reflecting the graph of the original function across the line y = x, which helps visualize the relationship between the function and its inverse.

Graphing Techniques
Graphing techniques involve methods used to accurately represent functions and their inverses on a coordinate plane. This includes plotting points, understanding the shape of the function, and using transformations such as reflections. For one-to-one functions, recognizing the symmetry about the line y = x is crucial for correctly graphing their inverses.
