Absolute Value Parent Function Maximum And Minimum. On the interval -4 2 the minimum value of the function occurs at the vertex. Steps to Finding the Absolute Extrema on a Closed Interval ab.
There is also no absolute maximum value of f since the y values on the graph extend infinitely upwards. Use a comma to separato answers as needed. As usual ignore unneeded answer blanks and list points lexicographically.
If the function always takes non-negative values only then.
A fx 0 0. A fx 0 0. Max x J f x max max x J f x min x J f x because left-hand side and the right-hand side are trivially equal. The function is increasing on 0infty and decreasing on -infty0.
