Question

Is there an inverse for the function f(x)=6x^3+3, or is it not a one-to-one function?

Answer 1

it is a one-to-one function and it has an inverse

Answer 2

well, I'm taking a quiz, and these are my choices @helder_edwin
A) f^-1(x)=cubed root of x+3/6
B) f^-1(x)=cubed root of x-3/6
C) Not a one-to-one function
D) cubed root of (x/6)-3

Answer 3

If it is a one-to-one function, then it must be B. Right?

Answer 4

u have to solve for x the following equation
\[\large y=6x^3+3 \]

Answer 5

\[\large y-3=6x^3 \]
\[\large \frac{y-3}{6}=x^3 \]
\[\large x=\sqrt[3]{\frac{y-3}{6}} \]

Answer 6

So that's B. Correct?

Answer 7

yes

Answer 8

Yay! Thanks so much! I made a hundred on the quiz. God bless you! :D
