Reflection: Checks for Understanding Exponential and Logarithmic Functions: Unit Assessment - Section 1: Unit Assessment

 

As evidenced by the unit exam, I was really impressed that my students had a strong conceptual understanding of logarithms! Almost all of my students demonstrated on one question or another that they truly understood that you cannot take the logarithm of a negative number and that its domain is only positive numbers.

Throughout the entire unit I really stressed that logab = x is just a different way to write ax = b, so I hope that this had some affect on them and made them realize that no matter what value x is, b can never be a negative number.
