Answer:
Explanation:
Given the function:
We want to find the domain of f(z).
The domain of a rational function is the set of values of z at which the denominator is not equal to 0.
To find the domain of f(z), set the denominator equal to 0 to find the excluded values.
The excluded values of the domain are -3 and 4/3.
Therefore, the domain of f(z) is:
