A drawing of the coordinate plane with points
plotted on it.
The constant by which functions
are horizontally shifted from one another.
The vertical or horizontal movement of the graph of a
function without changing the
shape of the graph.
The vertical or horizontal changing of the graph of a
function such that its shape
changes, but its orientation does not--for a function f, f (0, 0) remains the
Vertical Line Test
A method to determine whether a given plotted line on a graph is a
function. If a vertical line can
be placed somewhere in the coordinate plane such that it intersects with the
graph twice, the graph is not a function. Two intersections with a vertical
line signify that for a given value of x, there are two possible values of f (x),
which by definition is impossible for a function.
