Final answer:
Due to typographical errors and disparate reference information, the specific algebraic functions question the student is asking cannot be deciphered, and therefore, a precise mathematical solution cannot be provided without further clarification.
Step-by-step explanation:
The student's question involves the manipulation and evaluation of algebraic functions, which appears to be from a mathematics subject likely at the high school level. Unfortunately, due to the obfuscation and typographical errors in the provided text, the specific math problems being asked about cannot be determined accurately.
The provided reference information is disjointed, and without additional context or a clear connection to a solvable algebra problem, we cannot provide a factual and accurate solution. Each line of the provided information appears to be fragments of different mathematical concepts or problems, which without being properly connected to a coherent question, does not offer actionable information for solving.
For instance, one segment of the reference, '13 z = 2.78', implies a solution to an algebraic equation, while another, 'Fxdx = -kxdx = -kx²', seems to reference calculus through the mention of an integral. As the connections between these pieces are not clear, clarification from the student would be necessary to provide accurate assistance.
