The given function values are these:



All of the missing values can be determined by simple calculations, or by bits of algebra....

(f-g)(-4): %28-2%29-%281%29+=+-3
(f/g)(-3): %28-5%29%2F%287%29+=+-5%2F7
f(0): g%280%29=-4; %28f%2Fg%29%280%29+=+3%2F2 --> f%280%29+=+-6
(f-g)(0): %28-6%29-%28-4%29+=+-2
g(1): f%281%29+=+-9; %28f-g%29%281%29+=+-13 --> g%281%29+=+4
(f/g)(1): %28-9%29%2F%284%29+=+-9%2F4
f(3) and g(3): this one requires a bit more work...
%28f-g%29%283%29+=+-5; %28f%2Fg%29%283%29+=+7%2F2
f%283%29%2Fg%283%29+=+7%2F2
f%283%29+=+%287%2F2%29%2Ag%283%29
f%283%29-g%283%29+=+%287%2F2%29%2Ag%283%29-g%283%29+=+%285%2F2%29%2Ag%283%29+=+-5 --> g%283%29+=+-2 --> f%283%29+=+-7
