This is an interesting class of functions, but not nearly interesting enough for calculus purposes. While I do spend lots of time pushing the idea of linear approximations on my students ...

Most of these models come in the form of a mathematical function ... but the graph will look better this way. Second, I want to make a graph that is linear. So let's compare our expected model ...

I did linear regression ... lowest point without making a graph? There is one important thing about the lowest point. Right before that lowest point, the function is decreasing.

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...
