The given function is f(x) = 3x^4 - 4x^3 - 12x^2 + 3 on the interval [-2, 3]. To find the locations of the absolute extrema, we need to follow these steps:
1. Find the critical values of the function f(x) on the given interval by taking its first derivative f'(x) and setting it equal to zero.
2. Determine the values of f(x) at the critical points and the endpoints of the interval.
3. Compare the values obtained in step 2 to identify the absolute maximum and minimum values and their locations on the interval [-2, 3].
The first derivative of the function f(x) is given by:f'(x) = 12x^3 - 12x^2 - 24xSetting f'(x) = 0, we get:12x^3 - 12x^2 - 24x = 012x(x^2 - x - 2) = 0This gives us three critical points x = 0, x = -1, and x = 2.
We evaluate the function f(x) at these points and the endpoints of the interval to get:
f(-2) = -99f(-1) = 10f(0) = 0f(2) = 54f(3) = 198
Therefore, the absolute maximum value of f(x) on the interval [-2, 3] is 198, which occurs at x = 3. The absolute minimum value of f(x) on the interval [-2, 3] is -99, which occurs at x = -2.
Given a function, to find the locations of the absolute extrema, we need to find the critical values of the function on the given interval, determine the values of the function at the critical points and the endpoints of the interval, and compare these values to identify the absolute maximum and minimum values and their locations. For the function f(x) = 3x^4 - 4x^3 - 12x^2 + 3 on the interval [-2, 3], we find the critical points to be x = 0, x = -1, and x = 2, and the values of the function at these points and the endpoints of the interval. We find that the absolute maximum value of f(x) on the interval is 198, which occurs at x = 3, and the absolute minimum value of f(x) on the interval is -99, which occurs at x = -2.
Therefore, the locations of the absolute extrema of the function f(x) = 3x^4 - 4x^3 - 12x^2 + 3 on the interval [-2, 3] are x = 3 (absolute maximum) and x = -2 (absolute minimum).

You are to create a base class called Animal, using the files animal.h and animal.cpp. You should then create a derived, or child, class called Rabbit. You should create the definition of the class Rabbit in a file rabbit.h and the functions for Rabbit in rabbit.cpp. You will also create a main program to be housed in rabbitmain.cpp. A Rabbit will have attributes as follows. Those attributes indicated with a * should be in the base class Animal and inherited by the Rabbit class. • Breed (string) • Weight (float) • Name (string)* • Gender ('m' or 'f')* • Spayed or neutered (yes/no) • Registration ID (alphanumeric like HZ123X) • Color description (this could be more than a single word) * • Other comments (also more than a single word) Both Animal and Rabbit will have the following methods • Accessors for all attributes • Mutators for all attributes • A default constructor that sets all data elements to O or blank text as appropriate A fully specified constructor that allows defining values for all attributes. The Rabbit constructor should obtain all needed data and provide necessary data to the Animal Constructor automatically. • A display method that will display all the info for a rabbit in a logical and well formatted way including labels for each of the attribute fields. The display method should be a virtual function in Animal that is overridden in Rabbit. The Rabbit display should use the functionality of the Animal display function. rabbitmain.cpp should perform the following actions • Dynamically allocate a vector to hold 3 Rabbits. Note that you will have to allocate the vector to be of Animal pointers in order for the virtual function to operate properly • Prompt the user for information about each of the three rabbits and store that information in one of the vector elements in the appropriate class levels • Print the information for each Rabbit using an iterator • Clean up all allocated space
To implement the given requirements, create a base class Animal with attributes name and gender, along with accessors, mutators, a default constructor, and a virtual display method.
Then create a derived class Rabbit with additional attributes, constructors, mutators, accessors, and an overridden display method. Finally, in rabbitmain.cpp, dynamically allocate a vector to hold 3 Animal pointers, prompt the user for rabbit information, store it in the vector, print the information using an iterator, and clean up the allocated memory. The code consists of three files: animal.h, animal.cpp, and rabbit.h. animal.h defines the Animal base class with attributes name and gender, along with accessors, mutators, a default constructor, a virtual display method, and a virtual destructor. rabbit.h defines the derived class Rabbit with additional attributes, constructors, mutators, accessors, and an overridden display method. The rabbitmain.cpp file dynamically allocates a vector to hold 3 Animal pointers, prompts the user for rabbit information, stores it in the vector using the appropriate constructors, and then prints the information using an iterator. Finally, it cleans up the allocated memory to prevent memory leaks.

BCD (Binary Coded Decimal) is a coding system that represents each decimal digit with a four-bit binary code. To convert the decimal number 273.98 to BCD, we convert each digit separately. The BCD representation of 2 is 0010, the BCD representation of 7 is 0111, the BCD representation of 3 is 0011, and the BCD representation of 9 is 1001. The decimal point remains as it is. Therefore, the BCD code for the whole number part of 273 is 0010 0111 0011, and for the fractional part .98 is .1001 1000. Combining these parts, we get the BCD representation of the decimal number 273.98 as 0010 0111 0011 .1001 1000. Thus, option d is the correct BCD code for the given decimal number.
