This lesson begins with a review of the vertex formula for a quadratic and looks at two quadratics- one a vertical shift of the other- to verify that correct vertex is obtained for any quadrati

The lesson begins with an emphasis on isolating the radical expression in a radical equation and then highlights the importance of checking for extraneous solutions that may be generated when t

The lesson begins with a discussion about growth factors and percent increase, leading to the presentation of the compound interest formula.

Beginning with a formal definition of an exponential function, the lesson then compares the graphs of increasing and decreasing exponential functions.

The lesson begins with an application problem to motivate the necessity and use of a logarithm. The formal definition linking logs and exponents is then introduced.

The properties of logarithms are presented after the corresponding laws for exponents are reviewed.
The lesson begins with population application problems looking at doubling time, the constant time that it takes for an exponentially modeled population to double.
This lesson introduces logarithmic scales as a means for plotting data that might otherwise be difficult plot due to their widely varying values.
Beginning with the definition of a polynomial, polynomial multiplication and degree of polynomial products are introduced.
The lesson begins with the definition of an algebraic fraction and then a quick review of the fundamental principle of fractions.
