Algebra and Function Concepts Review

The video tutorial covers a review session for the Keystone Algebra 1 exam, focusing on various algebraic problems. It includes solving problems related to bank accounts, plant growth, swimming pool drainage, function graphs, reading time, heart rate, and satellite altitude. Each problem is analyzed using algebraic methods, graphs, and equations to find solutions.
