Answer:
Only the given table represents a function. Option 1 is correct.
Step-by-step explanation:
A relation is called a function, if there exist a unique value of y for each value of x. It means for each input there exist a unique output.
A function is always a relation but all relations are not function.
In the given table for each value of x, we have unique value of y, therefore the given table represents a function.
In second relation, at x=-2, the values of y are y=10 and y=-7. For single x, there are more than one value of y, therefore the second relation is not a function.
In third relation, at x=6, the values of y are y=-2 and y=1. For single x, there are more than one value of y, therefore the third relation is not a function.
You get 2m+m-3n which simplifies to 3m-3n

Answer:
Step-by-step explanation:
Given
at 9 am temperature of the body is 
1 hr later temperature 
Temperature of room 
According to newtons law
Integrating
Now at 9 am i.e. t=0,
At 10 am i.e. t=1 hr T=89
Temperature of Normal human body is 
Taking log both sides
i.e. 5 hr and 16.2 min
i.e. victim murdered at 3 am and 43.8 min
