Question

let f(x)=sqrt[3]{x-5}. find f^-1(x).

Answer 1

y= mx+b

Answer 2

the answer would be f^-1(x)=(x+5)^3, right?

Answer 3

yeah

Answer 4

yeah

Answer 5

yes

Answer 6

Just making sure. Thanks!

Answer 7

no

Answer 8

no?

Answer 9

nope

Answer 10

assuming you don;t need to specify the valid domain of x

Answer 11

hold on

Answer 12

sorry - it shud be x^3+5

Answer 13

I mis-read your answer

Answer 14

if \[f(x)=\sqrt[3]{x-5}\]

then \[f^{-1}(x)=x^3+5\]

Answer 15

wait... hm...

Answer 16

i think it really depends on how you read it

Answer 17

these are the possible answers:
a) f^-1(x)=3x-15
b) f^-1(x)=(x+5)^3
c) f^-1(x)=x^3+5
d) f^-1(x)=5/3
e) f(x) is not one-to-one, therefore it does not have an inverse

Answer 18

c.

Answer 19

there is no other way to read it

Answer 20

@Zarkon and @agreene are right

Answer 21

ok could explain why C is the answer

Answer 22

reported

Answer 23

reported

Answer 24

mods can see deleted posts

Answer 25

sorry for the confusion @mariomintchev - I should not have rushed to the answer initially.

Answer 26

the point is that just because you delete a post doesn't mean it is gone forever

Answer 27

thats fine. just need an explanation.

Answer 28

Hmmm...

Answer 29

\[y=\sqrt[3]{x-5}\]
\[y=(x-5)^{1/3}\]
\[y^3=((x-5)^{1/3})^3\]
\[y^3=x-5\]
\[y^3+5=x\]
\[f^{-1}=x^3+5\]

Answer 30

It’s C.

Answer 31

right? is it c?

Answer 32

@MarkSolves has explained it for you

Answer 33

mark. we already have the answer. -_-
