Absolute Max/Min vs. Relative Max/Min
I am so confused about finding absolute and relative max/min values.
For example, in practice test no calculator section, #4a find the approximate max on [-5,5]. What is the correct answer, (5,500) or (-1,130)?
Continue #4, 4b, is there a absolute max value? and the same thing on the "I didn't want to go to the talk" sheet, #4a-4d.

It would be (5,500) because that is the highest point within that interval. Endpoints on the interval to count when the interval is in square brackets. This means that x can equal the given values. It says approximate because based on the scale it is hard to give an exact y value. (-1,130) is relative because it is the highest point before the curve goes downward between about [-3,1] However, the answer is still (5,500) because this is the highest value of y in the given interval.
Also if the graph goes off into iffiniti like a positively faced parabola there is no absolute maximum because the graph does not stop.
