Question
Let s(t) represent the value of Fakeblock stock in CAD at time t in weeks since Fakeblock
went public, where 0 <t< 6. The graph of the derivative y = s'(t) is below.
y = s'(t)
10
t (weeks)
-10
(a) What should the units on the y-axis be?
(b) List the appropriate values of t
i. The critical points of the stock value function s(t) are at t =
ii. The local minima of the stock value function s(t) are at t =
iii. The local maxima of the stock value function s(t) are at t =
iv. The inflection point(s) on the graph of s(t) are at t =
(c) Knowing the graph of s' above, when are the best times for an investor to buy and sell Fakeblock
stock?
I recommend buying the stock at
weeks after Fakeblock went public
and selling the stock at
weeks after Fakeblock went public.

Expert Solution
Step 1

Note:

There are many subparts in the question. So I will answer the first two of them.

Please other questions send separately.

Given:

s(t) represents the value of Fakeblock in CAD at time t in weeks.

The graph of the y=s'(t) is:

Advanced Math homework question answer, step 1, image 1

Step 2

(a) The unit on the y-axis is:

We have y=s'(t) which give the rate of change of the value of Fakeblock in CAD per week

Hence, the unit for the y-axis is the value of Fakeblock in CAD/week.

(b) Let the appropriate values of t:

(i) The critical points of the stock value function s(t) are at t:

The critical points of s(t) define as the points at which y=s'(t)=0

which gives the given graph.

t=2, t=4, and t=5

Hence, the critical points of the stock value function s(t) are at t:

t=2, t=4, and t=5
