Answer:
-4
Explanation:
f(x)= 4/4x+16
reduce denominator to find the vertical asymptote
4/4(x+4)
Now what makes x equal to zero?
x+4=0
x=-4
So if I were to plug in -4 it'd give me 0
As you can see in the graph the function will never approach x at -4
Also although not asked this function is just 4/4(x+4)
since u cancel the 4s
1/x+4
