Evaluate Logarithms and Graph Logarithmic Functions Lesson 7.4 “c” Los Altos High School

Agenda Faux Quiz Continue discussion of Lesson 7.4 Practice 7.4, page 504 # 28-34 all Homework: Do the graphing problems from homework 7.4b and complete the graphing worksheet.

Evaluate Logarithms and Graph Logarithmic Functions Practice: Simplify the expression: 11 log 11 𝑥 log 5 5 −2𝑥 log 3 81 𝑥 Find the inverse of 𝑦= 7 𝑥 Find the inverse of 𝑦=ln⁡(𝑥+2)

Evaluate Logarithms and Graph Logarithmic Functions Graphing: We have seen that the inverse of an exponential function is a logarithmic function and vice versa. That means that their graphs should reflect… no pun intended… that. Let’s pay attention to the domain and range of both graphs.
