SUMMARY

The Extreme Value Theorem applies to constant functions, such as y=1, where both the maximum and minimum values are constant across the entire domain. For a constant function f(x)=11 defined on the interval [-10, 10], the minimum value is 11, achieved for all x within that interval. This demonstrates that the theorem holds true, as the minimum and maximum values exist and are equal throughout the specified set.

PREREQUISITES
  • Understanding of the Extreme Value Theorem
  • Basic knowledge of constant functions in calculus
  • Familiarity with function notation and intervals
  • Concept of minimum and maximum values in mathematical analysis
NEXT STEPS
  • Study the implications of the Extreme Value Theorem on non-constant functions
  • Explore examples of continuous functions and their extrema
  • Learn about the Mean Value Theorem and its relationship to the Extreme Value Theorem
  • Investigate applications of the Extreme Value Theorem in optimization problems
USEFUL FOR

Students of calculus, mathematics educators, and anyone interested in understanding the properties of functions and their extrema in mathematical analysis.

How is Extreme Value theorem correct for a constant function such as y=1 , where is the maximum and minimum?
 
Physics news on Phys.org
The minimum and maximum are every where.
Recall that we say m is the minimum of f on a set A if it is true that
there exist a in A such that
f(a)=m and
m<=f(x) for all x in A

If we have for example
f(x)=11 for [-10,10]
we would say f has minimum 11 on [-10,10]
depending what we were trying to do we would might further say
The minimum of f is 11 and is achived for all x such that -10<=x<=10.
 
Thanx man! i got it.
