Question

Find the domain of the function.

g(x) = 3x/x^2-8
A. (-∞, ∞)
B. (-∞, -9) (-9, 9) (9, ∞)
D. (-∞, 0) (0, ∞)

Answer 1

Answer 2

(Domain is D, and Range is R)
You can tell the `D ≠ ±√8` because then the function is undefined, since the denominator is then equal to zero.
But for other than that, any real number fits.
So
D = (-∞,∞) , D≠ √8, -√8

Answer 3

you can re-write the ±√8 as ±2√2

Answer 4

so the answer would be a.

Answer 5

Yes, but with the restriction that I showed
