Consider the function ?(?)=(?^(4/5))*(?−3). This function has two critical numbers ?<?

1) Then ?= ? and ? = ?.

2) For each of the following intervals, tell whether ?(?) is increasing or decreasing.
(−∞,?]: ?
[?,?]: ?
[?,∞): ?

3) The critical number A is ? and the critical number B is ? (a relative maximum / a relative minimum / neither max nor min )
There are two numbers ?<? where either ?″(?)=0 or f″(x) is undefined.

4) Then C = ? and D = ?

5)Finally for each of the following intervals, tell whether ?(?) is concave up or concave down.
(−∞,?): ?
(?,?): ?
(?,∞): ?

5. For the function ?(?)=−3?^4 −12?^3 Find the domain and intercepts. Find the critical numbers, intervals where f (x) is increasing and decreasing, and any local maximum and local minimum points (find both coordinates). Find the intervals where f (x) is concave up and concave down and any inflection points (find both coordinates). Use this information to sketch the graph of f (x).

1. Find the critical numbers of the function f (x) = x^3− 12x in the interval [0, 3]. Then find the absolute maximum and the absolute minimum of f(x) on the interval [0,3]. 2. Using only the limit definition of derivative, find the derivative of f(x) = x^2− 6x (do not use the formulas of derivatives).

Consider the following function ?(?) = ?^ 4+ 2? ^3 + 8?^ 2+ 5? With the initial guesses of ?1 = −2, ?2 = −1, and ?3 = 1, find the minimum of the given function using parabolic interpolation. Perform five iterations, reporting Ɛa based on the location of the minimum (i.e. xopt) and not the actual minimum value. (Round the final answer to four decimal places.)

Consider two assets, A and B. A earns +4%, –5%, or +3%, in scenarios 1, 2, and 3. B earns –5%, +3%, or +4%, in scenarios 1, 2, and 3. Compute the expected rates of return and SD for each asset, A and B. Now, consider a portfolio of assets A and B called AB, where the investor holds fraction 62% of his portfolio in A and fraction (1-62%) in B. Compute the standard deviation of AB and report this...

Write a Python program that has a list of 5 numbers [2, 3, 4, 5, 6). Print the first 3 elements from the list using slice expression. a. Extend this program in a manner that the elements in the list are changed to (6, 9, 12, 15, 18) that means each element is times 3 of the previous value. b. Extend your program to display the min and max value in the list.
