# How do you find the domain and range of #f(x) = - ( 1 / ( x + 1) ) #?

##### 1 Answer

**Domain:**

**Range:**

Using **interval notations**

**Domain:**

**Range:**

#### Explanation:

We are given the function

To find the **Domain** of

We must remember that **Vertical Asymptote**

So, our **Domain** is

To find the **Range** of

Let us now observe our **original function**

We note that there is no **x term** in the **numerator(NR)**

Hence, the **degree** of **numerator** is ZERO(0).

The **highest degree** of the **denominator(DR)** is ONE(1).

We observe that **degree of the DR** **degree of the NR**

Hence, we conclude that **Horizontal Asymptote**

**Range:**

**Range** using **interval notations** is
