oday was inverse day! We are headed into a deeper exposure to exponential and logarithmic functions, which are inverses, so we are reviewing and/or learning about inverse functions.
By the end of class, can you answer these questions:
Can you describe inverse functions
a) in terms of composition of functions
b) algebraically
c) graphically
d) using math vocabulary like input, output, domain, and range.
AND what is a horizontal line test and why do we use it? What does it have to do with the concept of a one-to-one function?
We did a warm-up that is attached below.
After lunch, we did a graphing activity that is attached below.
Then we took a few notes over 1.9 (not much) ... really just looking at the examples in the textbook and how you would use them to do the homework.
HW #1 is pp 90-92: 1-6,10,15,18,21,29,30,37-40,55, 58, 61, 79, 83, 89,91-93. We will check it Tuesday in our short class.
You will get a copy of the 1.9 worksheet in class Tuesday. Quiz in first part of class on Thursday, Feb 27.
