Draw the graph of `f(x)=sec^(-1)(sec x)`

Explanation

To draw the graph of \( f(x) = \sec^{-1}(\sec x) \), we will follow these steps:

### Step 1: Understand the Function
The function \( f(x) = \sec^{-1}(\sec x) \) means we are taking the secant of \( x \) and then applying the inverse secant function.

### Step 2: Apply the Definition
From the definition of inverse functions, we know that:
\[
