Question 932962
f(x)=x^2+x-12 and g(x)= x-2 
f(x)-g(x) = x^2+x-12 -x + 2 =  x^2 - 2x - 10
.......
g(x)/f(x) = (x+4)(x-3)/(x-2)  Domain: All real numbers except x = 2 CANNOT divide by 2
......
as to the 'o'
gof(x) = (x^2+x-12) - 2  Putting f(x) in place of x in g(x)
fog(x) = (x-2)^2 + (x-2) - 12
simplify last two
