 For the function

(x)
sketched above, find

(a) values

http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bc%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15
for which
'(c) = 0
,

(b) values

http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bc%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15
for which
'(c)
does not exist,

(c) values

http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bc%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15
at which
(x)
is not continuous?

(d) Does the function reach every value between its absolute minimum value and its absolute maximum value?

Problems 3--5. The following functions are defined for all

http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bx%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15
. Find the critical numbers if they exist. Explain in a sentance how you do it.



(x) = x
.



(x) = x^3+3 x^2-24 x



(x) = |2 x+3|

 Find critical numbers for

(t) = root(t)(1-t)
where
> 0
. What will you do first?

 Find the maximum and minimum values of

(x) = 3 x+1
defined on the interval
3,6]
.

 Find the maximum and minimum values of

(x) = x^2+4
defined on the interval
-2,6]
.

 Find the maximum and minimum values of

(x) = sin (2x)+cos (2x)
on the interval
-pi/4, pi/2]
. Then graph the function to check your answers.

 Sketch the graph of

Does
http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bf%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15
have an absolute maximum value? If so for what values of
http://calculus.sfsu.edu/latexrender?src=%5Cbegin%7Bdisplaymath%7D+%5Ctextstyle%7Bx%7D+%5Cend%7Bdisplaymath%7D&type=png&size=15
is this maximum achieved?
