Final answer:
To evaluate f(0) without using a calculator, simply substitute x with 0 in the function f(x) = 3x - 3 to get f(0) = -3.
Step-by-step explanation:
A mathematical function is a relationship between a set of inputs (domain) and corresponding outputs (range) such that each input is associated with exactly one output. It is a rule or process that assigns a unique value to each input. Functions are fundamental in expressing and analyzing mathematical relationships.
To evaluate f(0) without using a calculator, we can simply replace x with 0 in the given function f(x) = 3x - 3.
Therefore, f(0) = 3(0) - 3 = 0 - 3 = -3.
So, f(0) = -3.
