If the functions are combined so that h(x) = f(x) - g(x), then the domain of the function h(x) is x >

hx=f(x)+x>gh

Step-by-step explanation:

so the hx will equal to f(x_ then you add another x which is less than gh so you put an equal or greater than sign to prove its greater.

hx would then equal to

hx=fx

then factorise the brackets

hx=f(x)

dont factorise hx but just fx

1/800 is the right answer
