The answer is 3, and then 3 again
Another way to ask this question: where the x-value of function g equals 12, what's the y-value?
remember that function notation is like so: f(x), g(x), h(x)... so the number in the parentheses is an x-value from the function.
look through your points and find the one that represents an x-value of 12. (12, 19) is the point, and 19 is your output--so, g(12) = 19.

Final Answer
y = 13.14%
The screenshots of the solution are:
(4,7) cause its moving to the positive x side flipping on y axis the rule is (x,y) -> (-x,y) flipping over x axis the rule is (x,y) -> (x,-y) where - is opposite in each equation like a 5 turns into -5 or -3 turns into 3
