To understand the concept of finding the second derivative of the function \( y = \frac{x^2 + 1}{x - 1} - 3x \), it’s important to first simplify and differentiate the function step by step. After simplifying the function, you’ll differentiate it once to find the first derivative \( y' \), and then differentiate that result to obtain \( y'' \). This second derivative will provide insight into the concavity of the function, which is crucial in analyzing its behavior. When solving for derivatives, a common mistake is to incorrectly apply the quotient rule or to forget to simplify the function before differentiating. Always double-check your simplifications and remember that differentiating terms carefully one at a time can prevent small errors from snowballing into larger ones. If you're unsure, reviewing basics of derivatives and practicing with simpler functions can boost your confidence.
