Answer:
Due to lack of parenthesis, the function can be written one of three ways:
g(x) = (x+1)/(x-2)
g(x) = (x +1)/x - 2
g(x) = x + 1/x - 2
It is also unclear if you are doing function composition, or multiplication;
I am also assuming you are plugging -3 into function h;
so then h(-3) = 4 - -3 = 4 + +3 = 7
In the first case you get 8/5
in the second case you get 8/7 - 2 = 8/7 - 14/7 = -6/7
in the third case you get 7 + 1/7 - 2 = 5 and 1/7 = 36/7
