Answer:
No, it is not
Step-by-step explanation:
Here, we want to check if what we have is a function
For a relation to be a function, the mapping must be one to one or many to one
This mean, for every x there must be one y or for every y, there must can be multiple x
But never is it that there are many y for a single x
Looking at the value 0
on the domain, we can see -2 and 1 as the values
Thus, this is not a function
Look up a Pizza Place Online; with a website preferably
Find the cost and diameter of each size (should be in any pizza menu)
Divide the diameter by the cost (Cost/Diameter)
ex: 4.99/12
=0.415833333 per inch
Do this for all the sizes and compare each of the sums.
The one with the lowest cost per inch would be the best deal.
Hope this helps!
