Sketch the graph of `f(x)=(x^(2)-1)/(x+1)`.

Explanation

To sketch the graph of the function \( f(x) = \frac{x^2 - 1}{x + 1} \), we will follow these steps:

### Step 1: Simplify the Function
First, we simplify the expression \( \frac{x^2 - 1}{x + 1} \). We can factor the numerator using the difference of squares:

\[ x^2 - 1 = (x - 1)(x + 1) \]
