Answer:
4 hours = 4(60)=240min
2 hours = 2(60)=120min
120<=x<=240
f(x)=1.20||x/2||
So your answer is :
F(X)=1.20||x/2||, if 120<= x<= 240
Put one dot on (0,-2) , (4,0), (-4,-4) connect the dots that is your graph line.
Slope is 1/2 and you is -4
Answer:
---- critical point
local minima
Step-by-step explanation:
Given
Required
Determine the critical point
Differentiate w.r.t x
Differentiate w.r.t y
Equate both to 0
Divide by 2
----- in both equations
Hence:
The critical point is:
Solving (b):
We have:
This is represented as:
Calculate the determinant
The critical point is at local minima
False, that is not greater than
