Database Performance

A software development team is working on improving the performance of a

database query optimisation tool. The tool is designed to analyse and optimise

SQL queries to improve database performance for a web application. The team

needs to understand, concept of slope of a function at a point to identify

critical areas where query performance can be enhanced. The team uses the

function, $f(x)=\frac{x+8}{(3x+1{)}^2}$ to help them determine the rate of change of query

execution time.a$.$ Calculate the rate of change of the function mentioned in the scenario

above at the point $(0,8).$

b$.$ What are some potential challenges or limitations associated with

using the concept of slope of a function at a point to optimize database

query performance?
