(Absolute) Maximums and Minimums

Sometimes when the domain of a graph is restricted, the absolute minimum and maximum change.

I've been graphing the restricted function on my CAS and just looking to find the new max and min.

Is there a way of finding the absolute max/min of a restricted function without the help of a graph?

Sub in end points and compare with when the first derivative = 0.

Whatever produces a larger/smaller y value is the absolute max/min.

for a domain of (-4,4) ;)
