Final answer:
Without the details of the piecewise function, it is impossible to evaluate f(-5), f(0), or f(3). Generally, evaluating a piecewise function involves applying the specific rule for the interval that contains the input value, but the lack of function information here precludes a specific answer.
Step-by-step explanation:
The student has asked about evaluating a piecewise defined function at specific inputs; however, the function itself is not provided in the question, making it impossible to give an exact answer.
Typically, to evaluate a piecewise function like f(-5), f(0), and f(3), you would need to look at the definition of the function and see which piece of the function is applicable for the values of x mentioned. Without the function details, this specific question cannot be answered.
In general, a piecewise function will have different rules for different intervals of x. If the function were provided, you would identify the correct interval for each input value, plug the input into the rule defined for that interval, and compute the result.
For example, if a function is defined as f(x) = x² for x < 0 and f(x) = 2x + 3 for x ≥ 0, then f(-5) would be computed using the x² rule resulting in 25, f(0) using the 2x + 3 rule resulting in 3, and f(3) using the 2x + 3 rule resulting in 9.
