if g(x)=x+1/x-2 and h(x)=4-x what is the value of (g•h)-(3)

Answer 1

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
