Which relation defined by a mapping diagram is not a function?

Mathematics

If one element in the domain mapped with more then one element in the range, the mapping is called one-to-many relation. One-to-many relations are not functions. Example: Draw a mapping diagram for the function f(x)=2x2+3 in the set of real numbers.

which of the following allows a figure to remain congruent as it rotates around a point in its plane. A: Reflectional symmetry,
Anettt [7]
I think the correct answer is option D. It would be rotational symmetry that allows a figure to remain congruent as it rotates around a point in its plane. It also known as a radial symmetry. A figure which has this type of symmetry would look the same after rotating the figure by any angle. The degree of this symmetry would range from 2 to any positive whole integer. It depends on the number of distinct orientations that the figure would look the same. Examples are the shapes such as rectangles, circles, squares, stars, hexagon, pentagon and all regular polygons.

Sylvie finds the solution to the system of equations by graphing. y = x + 1 and y = x – 1 Which graph shows the solution to Sylv
Alexeev081 [22]
The only solution is when y=y

x+1=x-1  subtract x from both sides

1=-1

This is never true so there are no solutions.  In this case it is due to the fact that both lines have the same slope and different y-intercepts.  This means that they are parallel lines that have a constant distance between them.
