Question

Which points must always be checked when finding absolute extrema on a closed interval \[a,b\]?

पर्याय

• Only interior points

• The endpoints \[a\] and \[b\]

• Only points where \[f(x)=0\]

• Only local maximum values

Answer 1

Endpoints must always be checked in closed interval problems. An absolute maximum or absolute minimum can occur at either endpoint.
