Answer:
1) Function
2) Set Notation
3) Domains: {-4, -2, -1, 1, 3, 4}
4) Ranges: {-3, -2, 0, 2, 3}
Explanation:
1) This is a function because the x-values are NOT repeated, and it passes the vertical line test.
2) This is a set notation because it has the symbol --> { } and it is "help define the elements of a set." You can search up "set notation" and you would get the idea. However, this is not an inequality because in inequality you would have, ex: x < 4 ≤ x
3) Domains mean the x-intercept. Remember to list domains from least to greatest!
4) Range means y-intercept. Remember to list the ranges from least to greatest! If a range is repeated then you do NOT need to re-write that number again.
