In Algebra, we learn about functions of various types. These functions are often seen in a
progression from least complicated (linear) to
most complicated (piecewise with nonlinear
parts). And then there are other types of
functions in-between: exponential, quadratic,
polynomial, radical, and logarithmic. But with all
their differences and unique properties, these
share a common trait of being functions that we
can graph in a coordinate plane.
What are some other things you can observe to
have that same quality of functions: unique, but
sharing a common trait or purpose?
