Question 162731: The funtions are f(x)=2x^2+5x+7 and g(x)=x^3 + 2
The directions say evaluate the following: and identify the domain of each
The question is (g-f)(x)
I got x^3-2x^2-5x-5 so far

--------------------------------------------------------
g-f(x) is g(x) - f(x)

you got it right.
the domain is all x since there is nothing that would make the answer imaginary (with square root of a negative) or undefined (divide by 0).
