These are my notes to easy understand for last minute revision

This paper mainly focuses on the level and nature of competition in the automotive industry, precisely car manufacturers’ market power in the United States. Market power is significantly related to the demand curve, which dictates the company’s discretion on its prices. The level of competition is connected to financial proficiency and industry cost-effectiveness (IBIS, 2020). Therefore, this report defines the factors that influence the automotive industry and firms within it, including th...

1 Problem 1 Solve the following recurrence relation using any method. Provide your answer in big-O notation: T(n) = 2T( n 2 ) + log(n) for n > 1, 0 otherwise • T(n) = O(n) • T(n) = O(nlogn) • T(n) = O(n 2 ) • T(n) = O(logn) 1.1 Rationale This recurrence relation can be tricky to solve using iterative substitution or tree-based methods. It’s best to use the Master theorem here. Recall the form: T(n) = aT(n/b) + f(n) Since f(n) = log(n) = n  where  < log2(2) = 1...

I took this course over the 2021 summer semester. I received an A with these notes that I took. The only chapter not covered is ANOVA because that chapter is optional and is not on any exam.
