We have a function g(y) that is defined as a group of ordered pairs (y , g(y))
To find the value of g(-2), we have to look if there is a pair where the first number (y) is equal to -2.
There is an ordered pair that is (-2,1).
As the functions have one and only one value in the image g(y) for each value in the domain (y), the value of g(-2) is g(-2)=1, as the order pair indicates.
Answer: g(-2) = 1
