f(x) = 3x +2 and g(x) = x -3 f(x) - g(x) will be the difference between those two functions. 3x + 2 - (x - 3) = 3x + 2 -x +3 = 2x + 5 The answer is B.5/25/2014 | Nicole H.

Answer: [tex]3x^2 - x + 3[/tex] and domain is the

Step-by-step explanation:

Here, [tex]f(x) = 3x^2[/tex] and g(x) = x-3

Thus, f(x) - g(x) = [tex]3x^2 - (x - 3)= 3x^2 -x +3[/tex]

Since, the polynomial always has the set of real number as its domain.

Since f(x) - g(x) is also a polynomial.

Therefore, the domain of f(x)-g(x) is the set of real number.
