Findlimx鈫�2-f(x).

Short Answer

Expert verified

The limitlimx鈫�2-f(x)is-鈭�.

Step by step solution

01

Step 1. Graph the function f(x)

We have been givenlimx鈫�2-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, let us consider the behavior of f(x)near x=2when approaching from the left side.

The graph approaches -鈭�as xapproaches 2.

That is,limx鈫�2-f(x)=-鈭�.
