Mathematical operations are often represented by specific words or phrases in word problems. Addition is represented by phrases such as 'in all', 'together', 'total', 'plus', or 'and', subtraction with 'less than', 'fewer than', 'minus', 'difference', or 'take away'. Multiplication may be represented by 'of', 'times', 'every', 'product', or 'at this rate', and division by 'per', 'each', 'out of', 'ratio of', 'quotient', or 'separated equally'.
Mathematical operations often have keyword phrases associated with them. If you're asked to determine which operation a particular word or phrase represents, here's a simplified list:

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.
Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.
Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

Answer:
The graph that represents a cubic function is:
Graph A.
Step-by-step explanation:
We know that for the graph of a cubic function it satisfies the property that:
Graph B:
It is a graph of a linear function.
Since a graph of a linear function is a straight line.
Graph C:
It is a graph of a quadratic function.
Since both the ends of the graph are in the same direction.
Graph D:
It is also a graph of a linear function.
As the graph is a straight line.
Graph A:
It is a graph of a cubic function.
Since it satisfies all the above properties.
