Question

I am drawing a problem, can someone please help me

Answer 1

IT SAYS TO FIND F-1 (X) IN F(X)=^3 SQ X-8 AND SIMPLIFY. cAN ANYONE HELP ME

Answer 2

PLEASE HELP ME WITH THIS PROBLEM.....iM HAVING PROBLEMS\[f-1(x) ........f(x)=^{3}\sqrt{x-8}\]

Answer 3

So we want to find \(f^{-1}(x)\) and we have \(f(x)= \sqrt[3]{x-8}\)?

Answer 4

The solution is to find set \(f(x) = y\) and solve for \(x\) in terms of \(y\).

Answer 5

\[ \Large
\begin{array}{lcl}
y &=& \sqrt[3]{x-8} \\
y^3 &=& (\sqrt[3]{x-8})^3 \\
y^3 &=& x-8 \\
y^3 +8 &=& x-8+8 \\
y^3 +8 &=& x \\
f^{-1}(y) &=& y^3+8 \\
f^{-1}(x) &=& x^3+8
\end{array}
\]

Answer 6

Well, start with a simple view end it with a large one!
