Which of the following functions is guaranteed to have both a maximum and minimum value on the closed interval [0, 2π]?
A.f(x) = tan(x)
B.f(x) = 1/x
C.f(x) = sin(x)
D.f(x) = ln(x)
Explanation
Core Concept
The Extreme Value Theorem states that if a function is continuous on a closed interval, then it must have both a maximum and minimum value on that interval. Among the options, sin(x) is the only function that is continuous on the closed interval [0, 2π]. The other functions either have discontinuities in this interval or are undefined at some points.
Correct Answer
Cf(x) = sin(x)
