C: 2
Step-by-step explanation:

Start with the parentheses first
4.6 -4.4+7.8 then calculate from left to right
= 0.2+7.8 = 8
All it takes for a relation to be a function is for each possible first number of a pair there's only one possible second number.
So if any of the sets has two pairs with the same first number, that one's not a function.
The last one has (3,2) and (3,5) so isn't a function.
Step-by-step explanation:
Volume of figure=length×width×height
=(1/2)×(1/2)×6
=0.5×3
=1.5m³
