    Ok, that method's a bit less work. So you're given a parabola in vertex form: \[f(x)=1+(x+3)^2\] \(f(x)\) has vertex (an extreme value point) at \((-3,1)\). \(-3\) is not in the interval \(-2<x<6\). So, you have something that looks like this: |dw:1371696732887:dw| This means that only the endpoints of this interval will contain the extreme values.

    Which means you have only to check \(f(-2)\) and \(f(6)\).
