Homework Statement
Show the problem f(x)=((x-a)^2)*((x-b)^2) + x take on a value of a+b/2
for some x?
The problem involves the function f(x)=((x-a)^2)*((x-b)^2) + x and seeks to demonstrate that it can take on the value of (a+b)/2 for some x. The context is rooted in continuity and potentially the application of relevant theorems.
There is an ongoing exploration of the function's values at specific points, with some participants expressing confusion about the relationship to (a+b)/2. Hints about the intermediate value theorem have been introduced, suggesting a potential direction for the discussion.
Participants are grappling with the definitions and implications of the function's values at a and b, as well as the continuity of the function. There is a noted lack of clarity regarding how these relate to the desired outcome of (a+b)/2.
Dick said:What are f(a) and f(b)?? Can you think of a theorem that might apply??
fastblue said:Have no idea...
How do I do that, can you show me.Dick said:What are f(a) and f(b)? Work it out!

Thanks
fastblue said:so that gives you (a-b)^2 + a and (b-a)^2 + b
so what do u do next.
fastblue said:I just put in a for x and b for x, its obvious, what is wrong with it...?
fastblue said:0 I guess?
