on $f(x)=\frac{x}{3}+10$, find $f^{-1}(x)$
Final Answer: \(f^{-1}(x)=\boxed{3x-30}\)
Step 1 :Given the function \(f(x)=\frac{x}{3}+10\), we want to find the inverse function \(f^{-1}(x)\).
Step 2 :To find the inverse of a function, we switch the roles of x and y in the original function and then solve for y.
Step 3 :Replace \(f(x)\) with x in the function \(f(x) = \frac{x}{3} + 10\), we get \(x = \frac{y}{3} + 10\).
Step 4 :Solving for y, we get \(y = 3x - 30\).
Step 5 :Therefore, the inverse function of \(f(x)=\frac{x}{3}+10\) is \(f^{-1}(x)=3x-30\).
Step 6 :Final Answer: \(f^{-1}(x)=\boxed{3x-30}\)
