Question

The graph shown below expresses a radical function that can be written in the form f(x)=a(x+k)^1/n+c. . What does the attached graph tell you about the domain and the range of this function?

A. The domain is [c, ∞) & the range is [-k,∞)
B. The domain is [-k,∞) & the range is (-∞,c]
C. The domain is (-∞,∞) & the range is (-∞,∞)
D. The domain is (-∞,k] & the range is [c,∞)

Answer 1

B!
I think T-T

Answer 2

not 100% sure though

Answer 3

process of elimination c and d are wrong just look at the domain from - infinity

Answer 4

and look at A it says the range is + infinity

Answer 5

which clearly needs to be - infinity

Answer 6

oh okay so therefore only B would be correct?

Answer 7

yep :D

Answer 8

Woo!

Answer 9

YAY! :D thanks guys!!! :)

Answer 10
