14.7 Intermediate and Extreme Value Theorems
Here you will use continuity to explore the intermediate and extreme value theorems.
While the idea of continuity may seem somewhat basic, when a function is continuous over a closed interval like
x∈[ 1 , 4 ], you can actually draw some major conclusions. The conclusions may be obvious when you understand
the statements and look at a graph, but they are powerful nonetheless.
What can you conclude using the Intermediate Value Theorem and the Extreme Value Theorem about a function that
is continuous over the closed intervalx∈[ 1 , 4 ]?

TheIntermediate Value Theoremstates that if a function is continuous on a closed interval anduis a value between
f(a)andf(b)then there exists ac∈[a,b]such thatf(c) =u.
