# Practice Demo

**Find the limit if it exists. If the limit cannot be specified as a constant or infinity, enter $_DNE_$.**

$$\lim_{x\to 4 }{4\log_{2}(|-4+x|)}$$

Preview your answer:

``

**Hint 1:** We can graph the function $_4\log_{2}(|-4+x|)_$ to see what happens near $_x=4_$:

**Solution:**

From the graph, we can see that:

$$\lim_{x\to 4 }{4\log_{2}(|-4+x|)} = -\infty$$
