You see if the graphs passes the vertical line test.
if any vertical line passes through more than one part of the graph then its not a function - just a relation.
Answer:

Step-by-step explanation:
Let p be the number of identical packages.
We have been given that each package has a mass of 37.4 kg, so weight of p packages will be 37.4p.
The total mass of Renna and her load of identical packages is 620 kg.
We have been given that the mass limit for the elevator is 450 kg. This means that Renna can remove p packages from 620 kg such that 620 minus weight of p packages will be less than or equal to 450 kg.
We can represent this information in an inequality as:

Therefore, the inequality
can be used to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
It would be ft3 because its a cone shape and you multiply the circumference by the height and you’ll get the volume
