Let's evaluate each statement regarding areas:
-
Areas can be used to shade a region of any shape.
True: Areas can generally be used to shade regions of various shapes, depending on the graphical tool or context being used. -
Each palette icon will always allow you to drag only one fill area onto the graph.
False: Typically, palette icons can allow for multiple fill areas, depending on the software or tool being used. This statement may not be universally true. -
Changing the position of other objects on the graph may change the shape of the possible regions you may fill.
True: If other objects or shapes on the graph are moved, it can indeed alter the available regions for shading or filling, affecting what areas can be filled.
Therefore, the true statements are the first and third ones.
