Mrs. Downey covers Algebra 2 Chapter 7, focusing on exponential and logarithmic functions. The video includes graphing exponential functions, modeling population growth, using graphing calculators, evaluating exponential expressions, and solving both exponential and logarithmic equations. Key concepts such as the change of base formula and properties of logarithms are also discussed.
