<span>When rounding to the nearest ten, look at the number in the ones place. If the number is below five then the number in the tens column would stay the same, so your answer would be 360. If the number in the ones column is five or above the number in the tens column would round up, so the answer would be 370.
When rounding to the nearest hundred, look at the number in the tens place. If the number is below five then the number in the hundreds place would stay the same, so your answer would be 300. If the number in the tens place is five or more then you would round up, so the answer would be 400.</span>
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}
