1 Sketching Functions We are now going to use the concepts in the previous sections to sketch a function, find all max and min ( relative and absolute ), and identify any inflection points.

2 Sketching Functions We are now going to use the concepts in the previous sections to sketch a function, find all max and min ( relative and absolute ), and identify any inflection points. Absolute maximum – a relative maximum with the highest value within a given interval Absolute minimum – a relative minimum with the lowest value within a given interval
