Maximum value of the function f(x) = 1 - {x} / 3 + {x} is where {.} denotes the fractional part of (x)
Answers
Answer:
The maximum value of fractional part of x tends to 1 but is never 1 actually. Its lowest value is 0 though.
f

(x)=
(1+{x})

.
This is always positive. So f(x) is an increasing function.
Hence minimum value of the function is at x=0. f(x)=0
Maximum value of f(x) is as {x} tends to 1. The limiting value of the fuction is

but it is never actually attained by the function
Answer:
The maximum value of the function is 1
Step-by-step explanation:
The given function is
We can rearrange it in the following way
We have to find the maximum value of the above function.
For any function or expression to be maximum,
its denominator must be minimum.
Hence,
for our function 3+{x} must be minimum.
The range of {x} is
Hence its minimum value is zero.
Therefore,
the minimum value of 3+{x} is
Hence,the maximum value of our expression becomes
Therefore,
the maximum value of the function is 1
