Understanding the Concept of Inverse Functions
In the realm of mathematics, functions play a pivotal role in representing relationships between variables. The inverse of a function, denoted as f^{1}(x), is a function that undoes the original function. In other words, if we apply the original function to a value x and then apply its inverse to the result, we get back the original value x.
Deriving the Inverse of y = 16x^{2} + 1
To find the inverse of y = 16x^{2} + 1, we embark on a mathematical journey involving several steps:

Interchanging y and x:
As the first step, we interchange the roles of y and x, transforming the equation into x = 16y^{2} + 1.

Isolating y:
Our goal is to solve for y, so we rearrange the equation to isolate y on one side:
16y^{2} = x – 1

Dividing Both Sides by 16:
To simplify the equation further, we divide both sides by 16, yielding:
y^{2} = (x – 1)/16

Taking the Square Root of Both Sides:
To eliminate the square of y, we take the square root of both sides, resulting in:
y = ±√((x – 1)/16)

Simplifying the Expression:
We simplify the expression inside the square root by factoring out a 1/4:
y = ±√(1/4 * (x – 1))
y = ±(1/4)√(x – 1)
