Example TSAGEHor.0: Suppose $y$ is a function of $x$ given by
the equation $y = f (x) = 2x+ 3$.
The table, graph, and mapping diagram of this function have been
created using SAGE.
In this mapping diagram, the axes are horizontal and the arrows
point vertically.
This visualization is not preferred:
- To match the table, the table would have to be laid out
horizontally.
- It will match the X axis on the graph, but not the Y axis on
the graph.
- This does not match with an interpretaion of the function
value as an object.s height above,ground level.
