I know D is right but not sure about the others

OpenStudy (anonymous):

@random231 what? how?

OpenStudy (anonymous):

D is correct as well as C

OpenStudy (anonymous):

A is ambiguous as to what they men by "looks like".

OpenStudy (anonymous):

What about b?

OpenStudy (anonymous):

is it also correct

OpenStudy (anonymous):

B has a range where 1/2cbrt(x) has a range TWICE as large

OpenStudy (anonymous):

oh so not correct?

OpenStudy (anonymous):

Wait, they have the same sized range.

OpenStudy (anonymous):

One is just stretched out differently. Regardless, it is not correct.

OpenStudy (anonymous):

the defintion of (x-k) means shifted right by k unit in any equation. the same thing goes for ax where if 0<a<1, it will be a vertical shrink of the value a

OpenStudy (anonymous):

And if what I said before is true, D is true. D can't be true but B is correct.

OpenStudy (anonymous):

Wait what? D can't be true?

OpenStudy (anonymous):

No D is true and it is the reson why B is not true

OpenStudy (anonymous):

I hve to go, but I say C and D are the only true ones let me know how it goes later

OpenStudy (anonymous):

okay thanks! :)

OpenStudy (anonymous):
