Find the domain and range of the following relations:
(-3,2) (-2,6) (-1,-2) (0,-2)

Domain: {-3,-2,-1,0}

Range: {2,6,-2}

Step-by-step explanation:

The number in front are domain, for example: (-3,2) -3 which is in front is the domain and 2 which is in the back is the range.

Estimate the sum in two different ways:

A) By rounding off to the highest place value (hundreds):

 368 = 400  (3 hundreds is the highest place value)

 231 = 200 (2 hundreds is the highest place value)

 400 + 200 = 600

B) By rounding off to the second highest place value (tens):

   368 = 370

   231 = 230

   370 + 230 = 600

Hope this helps!
