Question

Find the inverse of the function.

f(x) = the cube root (x /7 )- 9

Answer 1

\[f(x)=\sqrt[3]{\frac{ x }{ 7 } - 9}\]

Is This The Equation?

Answer 2

No the cube root is only for x/7

Answer 3

Answer 5

Kind of here are the possible answers Find the inverse of the function.

f-1(x) = 21(x + 9)

f-1(x) = [7(x + 9)]^3

f-1(x) = 7(x^3 + 9)

f-1(x) = 7(x + 9)^3

Answer 6

Not Positive on This One But I'd Guess The Last One. @jim_thompson5910 Help?

Answer 7

I have one more question after this one if we can solve this one if want to help me on it.

Answer 8

\(\bf \Large f(x) = y=\sqrt[3]{\cfrac{ x }{ 7 } }- 9\\
f^{-1}(x) = y^{-1} \implies \Large x=\sqrt[3]{\cfrac{ y }{ 7 } }- 9\)

Answer 9

you just switch the variables, and then solve for "y"

Answer 10

What do you mean switch the variables?

Answer 11

\(\bf \bf \Large f(x) = \color{red}{y}=\sqrt[3]{\cfrac{ \color{blue}{x} }{ 7 } }- 9\\
f^{-1}(x) = y^{-1} \implies \Large \color{blue}{x}=\sqrt[3]{\cfrac{ \color{red}{y} }{ 7 } }- 9\)

Answer 12

DO I multiply them I will fan you if you tell me what the answer is by explaining it step by step
