For any fraction, if the denominator is zero -- the fraction is undefined.
.
Therefore for your fraction:

.
The restricted value(s) of x would be when:
x-4 = 0
Solving for x:
x = 4 (this is the only restricted value)

8x/(x-4) restricted values are values of x that make denominator =0 (division by zero isn't allowed)
lets check when denominator is = 0 ----> x-4=0 that happenes when x=4
Then the restricted value is 4
