There is not a given equation nor ordered pair, so it is impossible to answer this question. I apologise.
Answer:
find the inverse
exchange x for y and y for x
y=2x
then
x=2y---------> clear y
y=x/2
f−1(x)=x/2
for x=32
f−1(32)=32/2----------> 16
the answer is 16
The first one. X is greater than or equal to -1
