(U2) Lesson 4 - "Exponents Rule!" - JAMES TAYLOR | Library

Today's Learning Goal:
Use properties of exponents to rewrite exponential expressions.
Surface meaning for fractional exponents and their relationship to radicals in the context of examining an exponential function.
Reminders:
Discrete functions have distinct and separate values and are used for things that can be counted. (countable)
Continuous functions can have any value within a specific interval and values are connected. (measureable)
Domain of a function: The numbers that can be used as possible inputs
Today's Materials:
