Let

f (x) = \frac{\sqrt{x + 3}}{x^{2} - 25}

. Which of the statements about the domain of the function

f

is true?

D (f) = [- 3; 5) \cup (5; \infty)

D (f) = (- 3; 5) \cup (5; \infty)

D (f) = (- \infty; - 5) \cup (- 5; 5) \cup (5; \infty)

D (f) = (- \infty; - 5) \cup (- 5; - 3) \cup (- 3; 5) \cup (5; \infty)
