Step-by-step explanation:
2 is a value of x that would not make the set a function because a function can't have multiple coordinates wit hthe same domain (x-coordinate). 2 is a domain that has already been used in the point (2,7). If this is used in (x,5), the point would become (2,5) and repeat a domain.
Note:

Answer:
Step-by-step explanation:
121b^4 - 49 is a "difference of squares."
Formula for factoring a "difference of squares:"
a² - b² = (a - b)(a + b)
So: rewrite your 121b4 - 49 as 11²b^4 - 7² = (11b²)² - 7²
= (11b² - 7)(11b² + 7)
This answer matches the last of the four given answer choices.
