Step-by-step explanation:

I don't say u must have to mark my ans as brainliest but if it has really helped u plz don't forget to thank me my frnd..

Hey

Let R be a relation from A to B.

Then, the set of first components or the set of elements of A are called domain and the set of second components or the set of elements of B are called the Range.

For example:

If R:(A,B)={(1,1), (2,4), (3,9)} then,

Domain={1,2,3}

Range={1,4,9}

Good luck on your assignment

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

the answer for this question is a= 13,622.84
