Find $f + g$, $f - g$, $fg$, and $\frac{f}{g}$. Determine the domain for each function. f(x) = $\sqrt{x}$; g(x) = x - 19 $(f + g)(x) = \sqrt{x + x - 19}$ (Simplify your answer.) What is the domain of f + g? A. The domain of f + g is $[0, +\infty)$. (Type your answer in interval notation.) B. The domain of f + g is { }. (Use a comma to separate answers as needed.) C. The domain of f + g is $\emptyset$. $(f - g)(x) = \sqrt{x} - x + 19$ (Simplify your answer.) What is the domain of f - g? A. The domain of f - g is { }. (Use a comma to separate answers as needed.) B. The domain of f - g is $[0, +\infty)$. (Type your answer in interval notation.) C. The domain of f - g is $\emptyset$. $(fg)(x) = x\sqrt{x} - 19\sqrt{x}$ (Simplify your answer.) What is the domain of fg? A. The domain of fg is (Use a comma to separate answers as needed.) B. The domain of fg is (Type your answer in interval notation.) C. The domain of fg is $\emptyset$.

          Find $f + g$, $f - g$, $fg$, and $\frac{f}{g}$. Determine the domain for each function.

f(x) = $\sqrt{x}$; g(x) = x - 19

$(f + g)(x) = \sqrt{x + x - 19}$ (Simplify your answer.)
