Step-by-step explanation:
The domain of a function is the set of -values.
see explanation below
(1) × = = 0.2
(2) × = = 0.24
(3) 2 = 2 + = 2.75
(4) 3 = 3 + 0.9 = 3.9
(5) 1.25 = 1 =
(6) 3.29 = 3 =
(7) 0.65 = = in simplest form
(8) 5.6 = 5 = 5 =
(9) he is incorrect
× = = 0.6 ≠ 3.5
nope its not a function
A and D
3 - 5x > 2
= -5x > 2-3
= -5x > -1
= x < 1/5
