Answer:
2nd option
Step-by-step explanation:
note that
5n ← generates multiples of 5, that is
5 × 1 = 5
5 × 2 = 10
5 × 3 = 15
5 × 4 = 20 , etc
5, 10, 15, 20, ....... are multiples of 5
but 5n + 1 does not generate multiples of 5 as
5 + 1 = 6
10 + 1 = 11
15 + 1 = 16
20 + 1 = 21
6, 11, 16, 21 are not multiples of 5
Answer: x-4>-9 or x-4<9
Hello!

Hope that helps!
Sets D, E
Sets D and E both have repeated x-values , thus making them a relation not a function.
i think 4 or 40
