The problem involves a function defined as f(x) = x^3 and asks to show that f(a,b,c) = a+b+c. Participants are questioning the validity and meaning of the expression f(a,b,c), as it appears to conflict with the function's definition which accepts a single argument.
The discussion reflects a lack of consensus on the problem's validity, with multiple participants asserting that the question does not make sense as stated. Some have provided links to past exam papers to support their claims, while others emphasize the need for clarity on the definition of f(a,b,c).
Participants note that this question appeared in a formal examination context, raising concerns about its legitimacy and the expectations placed on students regarding its interpretation.
As stated here, the question doesn't make sense. Your function f takes a single argument, so you could evaluate f(a), or f(b), or f(c), but not f(a, b, c).abrowaqas said:Homework Statement
If f(x) = x^3,
show that
f(a,b,c) = a+b+c
