The inverse of the function
\(f(x) = (1)/(4)x + 10\) is \(f^(-1)(x) = 4x - 40\), making option B,
\(f^(-1)(x) = 4x - 40\), the correct choice.

To find the inverse of the function
\(f(x) = (1)/(4)x + 10\), you switch the roles of x and y and then solve for y.

1. Replace f(x) with y:


\[y = (1)/(4)x + 10\]

2. Swap x and y:


\[x = (1)/(4)y + 10\]

3. Solve for y:


\[4x = y + 40\] \[y = 4x - 40\]

Therefore, the inverse function is:


\[f^(-1)(x) = 4x - 40\]

So, the correct answer is:

B.
\(f^(-1)(x) = 4x - 40\)
