Question

which is true about the function below?

1/ (sqroot)x+10

a) domain= [-10, infinity), range = (-infinity, 0) U (0, infinity)

b)Domain=(-10, infinity), range=(0, infinity)

c)Domain=(-10, infinity), range= (-infinity, infinity)

d)Domain=[-infinity, 0), range=(0, infinity)

Answer 1

x + 10 = 0
x = -10
range is all real numbers
so C.

Answer 2

You sure the range is C?
