In the following the symbol for the first derivative is dy/dx or Y and the symbol for the second derivative is d 2 y/dx 2

In the following the symbol for the first derivative is dy/dx or Y’ and the symbol for the second derivative is d²y/dx² or Y”, all of which are standard symbols.

Y = X³ –X² +3

X	-.333	-.25	0	.25	.333	.667	1
Y
dy/dx
d²y/dx²

A function is given above. The table gives several pre-selected values of the independent variable (X). Use all of these to have enough to answer questions for this assignment.

Calculate the Y value corresponding to each X value in the table. Write the Y value and its sign (+ or -) calculated in the cell below its X value. Pick any three of the X values and on a separate worksheet, show how you calculated its Y value. Use these X,Y pairs also if you chose to do the bonus option.
Find the critical values among the given X values by:
Correctly finding the first derivative of the given function. Write dy/dx here ________________ Show how you found the derivative on the worksheet (this is half the credit for this question).
Using the derivative from (2a) solve it for all the X values that make the derivative equal zero. Show your work on the worksheet and also write “0” in the cell of the dy/dx row for the X value where dy/dx = 0. There may be none, one, or two such. (this is the other half credit).
Find additional critical values among the X values by:
Correctly finding the second derivative of the given function. Write d²y/dx² here ___________ Show how you found this second derivative on the worksheet (this is half the credit for this question).
Using the second derivative from (3a) solve it for all the X values that make d²y/dx² equal zero. Show your work on the worksheet and also write “0” in the cell of the d²y/dx² row for the X value(s) where d²y/dx² = 0. There may be one, or two such. (this is the other half credit).
