Build a sign chart

Therefore,

#### Explanation:

As the expression is undefined for

Before we work on the expression algebraically, let's draw a graph:

graph{-(x+1)/(x+4) [-13.21, 6.79, -5.72, 4.28]}

Based on the graph we can see that the unequality is fulfilled for

Let us clean up the expression to make it easier to work with:

An equivalent expression is

As this is undefined for

**1) #x> -4#:** As

Therefore

**2) #x< -4#:** Now the denominator

As the starting point was that
