Question

Which of the following statements are true?
(more than one answer)
F(x)=1/2 √x has the same domain and range as f(x) = cubed x.
The graph of f(x) = cubed x / 2 looks like the graph of f(x) = cubed x, but will shrink it vertically by a factor of 1/2.

The graph of f(x) = cubed x / 2 looks like the graph of f(x) = cubed x , but will shrink it horizontally by a factor of 1/2.

The graph of f(x) = cubed x / 2 does not look like the graph of f(x) = cubed x because the roots are different.

Answer 1

cubed x is just \[\huge \sqrt[3]{x}\]

Answer 2

not good wid horizontal shrink/stretch stuff but il try...
take a snapshot and attach if psble :)

Answer 3

Okay here it is

Answer 4

I think its option B and D.

Answer 5

we can strike off first option as \(\sqrt{x} \) domain is only nonnegative. but \(\sqrt[3]{x}\) domain is all all reals

Answer 6

yes B is correct, 1/2 shrinks the graph vertically.
let me see others :)

Answer 7

okay.

Answer 8

yup B and D !

Answer 9

Thank you :)
