Final answer:
The missing values for the set ((x, x+3, x-1), x is any real number) can be represented as (x-1, x, x+3).
Step-by-step explanation:
The set ((x, x+3, x-1), x is any real number) can be represented as ((a, b, c), z is any real number).
To find the missing values, we compare the given set to the options: a) (z, z+3, z-1), b) (x+3, x, x-1), c) (x-1, x, x+3), d) (x, x-1, x+3).
The set that matches the given set is option c) (x-1, x, x+3). Hence, the missing values are a=x-1, b=x, and c=x+3.
