Answer:
   Either of ...
- (x, y) ⇒ (-x, -y)
- Rotation 180° about the origin
Step-by-step explanation:
There are at least two ways to express the transformation that maps each coordinate to its opposite.
   1. reflection across the origin: (x, y) ⇒ (-x,-y)
   2. rotation 180° (either direction) about the origin.
Take your pick.

domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x =  = 2.4
 = 2.4
7x - 2.7 = 30.9 ⇒ x =  = 4.8
 = 4.8
7x - 2.7 = 41.4 ⇒ x =  = 6.3
 = 6.3
7x - 2.7 = 58.9 ⇒ x =  = 8.8
 = 8.8
7x - 2.7 = 68 ⇒ x =  = 10.1
 = 10.1
