4/1/2008 Algebra 1 - More Graphing Quadratics

Today we backed up a bit to discuss and do examples of graphing quadratic equations. We did 6 examples of graphing to add to the notes form before break.

Homework:
p. 505 66-70 all, p. 514 10-24 even
Sketch and graph y = 2x^2 - 5 and y=x^2 + 4x - 4

4/1/2008 Algebra 2 - Logarithmic Functions



Today's lesson focused on the inverse of exponential functions, logarithmic functions. We defined a logarithm, worked on rewriting exponential expressions as logarithms (and vice versa), familiarized ourselves with using a calculator to find common and natural logarithms, and then found the inverses of some exponential functions, which happen to be logarithmic functions. The video above shows some additional explanation and you will find the links above helpful as well. Click here to get some more insight into logarithms and their graphs.
