In this semester we’ve learned several topics such as linear functions, average rates of change and polynomial in the short-run and the long-run, exponential function, and quadratic functions. I don’t think pre-calculus has been much different than the math I learned in high school. Calculating the average rate of change was surprising to me because it was something new that I never learned. The most interesting idea was finding the roots. However the topic I had most trouble with was piecewise functions.

I think the idea Ill use the most is calculating the average rate of change. It is the change in the value of a quantity divided by the elapsed time. For a function, this is the change in the y-value divided by the change in the x-value for two distinct points on the graph. Something I would like to go differently moving forward is having the professor teach more using the white board instead of desmos.

What do you want to do differently going forward?
