Reflection: Student Feedback The graphs of logarithmic and exponential functions - Section 3: Exponential functions and logarthmic functions are inverses


The consensus of my students is that they hate logarithms.  My thought is that students dislike the functions because they do not understand how they relate to exponential functions. By doing the graphing activity students develop a deeper understanding of the relationship between exponential and logarithmic functions. I tell students that a logarithm is just the notation for the inverse of an exponential just like the square root is the notation for the inverse of x^2.

Students have negative attitudes towards topics they do not understand. Students do not understand how logarithms are used in the world. Before common core logarithms were taught by learning a process with little regard to the importance of logarithms in higher level mathematics and science.

The graphs of logarithmic and exponential functions

Unit 3: Exponential and Logarithmic functions
Lesson 1 of 11

Objective: SWBAT graph logarithmic and exponential functions using the key features of the graphs.

Big Idea: An understanding of the relationship between exponential and logarithmic functions is developed through analyzing graphs and identifying the domain, range, intercepts, asymptotes and end behavior of exponential and logarithmic functions.
