Outcomes
In this lesson you will
- explore graphs of arithmetic, quadratic, and higher degree power sequences
- use common differences to distinguish between arithmetic and power sequences
- use
, the
-level common difference, to determine the degree of a power sequence
- explore the relationship between
, the second-level common difference, and the coefficient a in the function
used to generate a quadratic sequence
By the end of this section students will be able to:
- demonstrate an understanding of patterns that are arithmetic, power, and geometric, and relate then to corresponding functions
- analyze tables and graphs to distinguish between linear, quadratic, and exponential relationships
- sketch graphs from descriptions, tables, and collected data
- determine the equation of a quadratic function using finite differences
Prerequisites
To be successful in this lesson, it would be helpful to know the following:
- use technology to graph linear and non-linear functions and to find the equation of the curve of best fit
