The set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.
<h3>When does a relation represents a function?</h3>
A set, or a relation, represents a function when <u>each value of x is mapped to only one value of y</u>.
In this problem, we have that option A represents a function, as:
- In option B, x = 2 and x = -2 are mapped to two values.
- In option C, x = 4 is mapped to four values.
- In option D, both x = 1 and x = 2 are mapped to two values.
Hence the set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.

Answer:
g(x) = -√(x -2) -1
Step-by-step explanation:
We note the domain of f(x) is x ≤ -1. The is the range of the function g(x).
The inverse function is the solution to ...
x = f(y)
x = (y +1)² +2
x -2 = (y +1)²
-√(x -2) = y +1 . . . . . . . we are interested only in the negative values
y = -√(x -2) -1
The inverse function is ...
g(x) = -√(x -2) -1
