A polynomial expression can only be categorized into a function if and only if a single input can only have one and only output. This means that there should be no more than one dissimilar values of y for the same value of x.
Evaluating the givens above, it can be observed that there are two -1's as an x-coordinate and it has two outputs, 0 and 1. Thus, we can remove either (-1,0) or (-1,1) for the relationship to become a function.
Answer:
Domain is all the values that go into a function, and range are the values that come out of that function
Step-by-step explanation:
A value is an integer, so when you have an INPUT (your domain) that makes a line/slope, an OUTPUT (your range) will be your outcome, aka your answer
Answer:
Bobby's economic profits for the day is $0.60.
Step-by-step explanation:
Bobby sells 20 glasses of lemonade for $0.20 per cup.
Amount earned = 
dollars
The average total cost is $0.17.
So, difference in selling amount and average = 
dollars
Therefore, Bobby's economic profits for the day is = 
dollars
Hence, the answer is $0.60.
