Answer:
Option C
{-1,3,5}
Step-by-step explanation:
A mapping is a subset of ordered pair (x,y) where x belongs to first set and y belongs to second set.
Hence a mapping is a subset of cartesian product AXB.
Here A = {-2,1,3,5} and
B = {2,4,6,8}
Ordered pair given by the mapping is
(-2,1) (3,6) and (5,8)
In other words, -2 is mapped on to 1, 3 to 6 and 5 to 8
Domain = set of elements in the I set which are mapped
= {-1,3,5}
Answer: First option.
Step-by-step explanation:
For this exercise it is importnatn to to remember the properties that are shown below:
1)
2)
Therefore, given the following expression provided in the exercise:
You can apply the properties mentioned before, in order to find an equivalent expression.
Therefore, you get:
Then the answer is the first option.
They are not all squares because a rhombus has all sides of equal length, but NO right angles. A square is a rhombus WITH right angles.
Hope that clears things up.
