Compare Functions to Determine the Better Buy

The video tutorial addresses a standardized math test question involving function comparison. It is divided into four parts, each focusing on different aspects of the problem. Part A involves determining the cost per shirt at a local store using a graph. Part B requires writing a function for the total cost of shirts from the local store. Part C involves creating a function for the cost of buying shirts online, including a shipping fee. Part D compares the total costs from both sources to determine the cheaper option. The tutorial concludes that buying online is more cost-effective.
