See, please, suggested decision:
When the line intersects the xy-plane, then parameter z=0, when does the xz - y=0 and when does yz, x=0. All the details are in attachment.
If it's possible, check arithmetic part.
Answer:
yes it is a function
Step-by-step explanation:
Mathematics
In mathematics, a function is a binary relation over two sets that associates to every element of the first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.
Add all the numbers:
32 + 33 34 + 34 + 36 + 38 + 38 + 38 + 40 + 42 = 365
There are 10 numbers.
Divide:
Total by how many numbers there are
Total = 365
Numbers = 10
365 / 10 = 36.5
The mean is 36.5
