Findlimx鈫�-4+f(x).

Short Answer

Expert verified

The limitlimx鈫�-4+f(x)is-2.

Step by step solution

01

Step 1. Graph the function f(x)

We have been givenlimx鈫�-4+f(x).

Now let us graph the function with the help of a graphing utility.

02

Step 2. Finding the limit from the graph.

In the graph, consider the behavior of f(x)nearx=-4when approaching from the right side.

The real value of f(-4)=1.

However coming from the right side, the value of the function approaches-2.

That islimx鈫�-4+f(x)=-2.
