Final answer:
Input values should be checked for appropriate range, reasonableness, and division by zero if division is necessary, so the answer is D) All of these. These steps ensure that inputs are valid and that computational results are reliable and accurate.
Step-by-step explanation:
When input values are being checked, they should always be evaluated for A) Appropriate range, B) Reasonableness, and C) Division by zero, if the division is taking place. Therefore, the correct answer is D) All of these. It is essential to check that inputs are within the expected bounds (appropriate range) of the problem to prevent errors. Inputs should also make sense in the context of the problem (reasonableness), such as not inputting a negative number for a quantity that should always be positive.
When dealing with division, we must make sure that we are not dividing by zero, as this is undefined and could cause computational errors or system crashes. These checks help prevent incorrect outputs due to invalid inputs, and they become more intuitive with experience.
Moreover, in terms of numeric calculations and measurements, the answers must be consistent with significant figures, particularly when performing operations like multiplication and division. This ensures that the precision of the calculated values is not overstated and matches the precision of the input data. With practice, anticipating reasonable ranges for answers before beginning a problem becomes feasible and highly beneficial.
