Functions and Non-Functions

Math Merge Seminar 1:Task

What observations can we make?

Graph Part

Non-Function
-symmetrical with x-axis
-seemed to have some closing points


Function
-symmetrical with y-axis
-seemed to have symmetry
-Go one way on the x-axis
(Don't go and come back)

What are some generalizations we can make about symmetry and how the symmetry is different for a non-function vs. a function?

Table Part

Non-Function



Function


Do you think you could draw a graph and be fairly confident it is a function? a non-function?

The class is still in disequilibrium of the meaning of a function.

Looking at the tables of functions and non-functions, what observations can you make?


Equation Part

Function
-Doesn't have a y^2
-2 or more variables


Non-Function
-Has a y^2
-2 or less variables
