Let f be a twice-differentiable function such that f′(1)=0 . The second derivative of f is given by f′′(x)=x2cos(x2+π) for −1≤x≤3 .

(a) On what open intervals contained in −1
(b) Does f have a relative minimum, a relative maximum, or neither at x=1 ? Justify your answer.

(c) Use the Mean Value Theorem on the closed interval [−1,1] to show that f′(−1) cannot equal 2.5.

(d) Does the graph of f have a point of inflection at x=0 ? Give a reason for your answer.

Ijust need with an idea of how to write it or example.1. for this assignment you will create a developmental timeline. the timeline should include significant events, or possible future significant events, from your entire life—from womb to tomb. you are encouraged to personalize your timeline with pictures, etc. for each incident or event that you list, you need to relate it to a concept developed by piaget, kohlberg, or erikson. for example, if one of your events is, “i said my first word, ball,” and you have this on your timeline at 15 months, you also need to say, “piaget’s preoperational stage.” along with each event you discuss, provide a brief description of its significance. score
