In PreCalc we continued working through the problems on the summer packet. We determined yesterday that domain and range, increasing/decreasing/constant intervals, as well as piece-wise defined functions need some more detailed study when they come up in our lessons. This isn't shocking to me as it is a common issue each year. The kids do have a firm grasp on finding zeros via factoring or graphing, end behaviors, maxima and minima as they apply to linear, quadratic, and polynomial functions. Our summer packet concludes with rational, radical, exponential, and logarithmic functions. There is also a little bit of right triangle trig thrown in. I expect most things in these areas will be things that they students aren't as comfortable with as they were taught late in the Algebra 2 class. We were also fortunate to have a foreign exchange student join our class yesterday. I can't wait to see what that adds to our class.
