is this right: i got x = (csc^-1(8)+pi)/2 + (pi)k

Let's analyze the given function and find the values of \( x \) where \( f(x) = 0 \).

The function is given by:

\[
f(x) = 3 + \tan\left(x - \frac{\pi}{3}\right)
\]

To find where \( f(x) = 0 \):

\[
3 + \tan\left(x - \frac{\pi}{3}\right) = 0
\]

Subtract 3 from both sides:

\[
\tan\left(x - \frac{\pi}{3}\right) = -3
\]

Now, let's solve for \( x \):

\[
x - \frac{\pi}{3} = \tan^{-1}(-3) + n\pi
\]

where \( n \) is any integer because the tangent function is periodic with period \( \pi \).

Now, solve for \( x \):

\[
x = \tan^{-1}(-3) + \frac{\pi}{3} + n\pi
\]

This is the general solution for \( x \) where \( f(x) = 0 \).

To verify your solution:

The expression you provided is \( x = \frac{\csc^{-1}(8) + \pi}{2} + k\pi \).

There seems to be confusion between your result and the correct general solution form. Specifically, the use of \( \csc^{-1}(8) \) is not consistent with the result needed for \( \tan^{-1}(-3) \).

### Key Points:
- \( \tan^{-1}(-3) \) is the correct inverse tangent for solving this equation, not the \( \csc^{-1}(8) \).
- The correct solution should be of the form \( x = \tan^{-1}(-3) + \frac{\pi}{3} + n\pi \).
