The picture shows the word power with subscript 2 of 8 equals 3 and power with subscript 5 of 25 equals 2, followed by nine more without the value for students to figure out.
#MathsToday
Today was day 1 of logarithms in #MHF4U so I presented students with this, inspired by James Tanton.
4 quadrants showing facts about exponential growth and decay functions
4 quadrants showing facts about a function and its inverse, including sketches
Logs disguised as powers
Started working with exponential & log functions in #MHF4U today. What do you remember about exponential functions? What do you remember about inverse functions? What is this power function doing? (credit James Tanton) Then we put it all together.
