Final answer:
Without the explicit functions for g and h or additional details about the composition goh, it is not possible to approximate the value of (goh)(3) with the information provided.
Step-by-step explanation:
The student has asked to approximate the value of (goh)(3). Without additional context or functions provided for g, h, and the composition goh, it is not possible to determine the value of (goh)(3). For these types of questions, one needs to either have the explicit functions for g and h or additional information about the behavior of their composition at a specific input value, such as 3. Therefore, unless more information is provided, an accurate approximation cannot be given for the options provided: A) 2.5, B) 3.5, C) 4.5, D) 5.5.
The rest of the given information does not seem to relate to the question about the function composition (goh)(3). Instead, they appear to reference various topics in chemistry, statistics, and measurement rounding, which are not directly applicable to the question at hand.
