The domain is going to be all ur x values...so the domain is { -4,-1,1,4 }....the range will be all ur y values...so the range is { -1,1,4} ...the reason there is only 3 numbers is because if the numbers repeat, u only have to write them once.
A function will not have any repeating x values....they can have repeating y values, just not the x ones. So if all ur x values are different, then it is a function. Therefore, this is a function.
If two parallel lines are cut by a transversal, the corresponding angles are congruent.

Answer:
A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = b/c
A = arccos(b/c) = arccos(2.5/6)
A ≈ 65.4°
