Answer:
The restricted value is x=0
Step-by-step explanation:
We have been given the expression
This is a rational function. We know that the rational expression is undefined if denominator is zero.
Here, we will use this fact to find the restricted value (s) of .
Restricted values means the values for which the function is not defined.
The given function is not defined if the denominator is zero.
12x =0
x =0
Hence, the restricted value is x=0
