Final answer:
The equivalent value of f(0) for the function f(x) = 1 - x is 1, which corresponds to choice b.
Step-by-step explanation:
The question asks us to evaluate the function f(x) = 1 - x at x = 0. To find the value of f(0), we simply substitute 0 for x in the function:
f(0) = 1 - (0) = 1
Therefore, the value that is equivalent to f(0) is 1, which corresponds to choice b. This evaluation is a basic exercise in understanding and applying the concept of a function as a rule that assigns to each input exactly one output.
