This assignment will assess your skills and knowledge on demonstrating algebraic operations, composition operations on functions and inverse functions, each with specific real-world applications. Algebraic operations are used in economics and physics, composition operations in computer science and physics, and inverse functions in cryptography and engineering. Understanding these concepts and their applications, answer the following questions clearly, showing step-wise solutions and providing reasons wherever necessary.
You are required to complete all the 4 tasks in this assignment. When you are instructed to make a graph in this assignment, please use

(i) Find the functional values to the algebraic operations , (fg)(x), fog(x), and gof(x) by explaining the way of performing operations. Show all steps of calculations.
(ii) Are fg, fog, and gof equal? Please explain your answer.
(iii) Find the domain and ranges of each of the 4 operations. Explain the procedure of finding the domain and range for each of above 4 operations.
Task 2. In a cutting-edge greenhouse, an advanced climate digital control system is installed based on a DC inverter that maintains the desired temperature in the green house. The system’s temperature control function is described by
where T represents the temperature inside the greenhouse in degrees Celsius, and C represents the desired control setting on the climate control system of DC inverter.
Based on that information, please provide answers to the following questions:
(i) Using the concept of the inverse function, determine the control setting (C) as a function of greenhouse temperature (T). Please outline all the steps clearly.
(ii)Discuss any practical limitations or considerations that may impact the functionality of the inverse function within the context of the greenhouse climate control system.
