Answer:
a) 
, b) 
, 
, c) , d)
Step-by-step explanation:
a) Let derive the function:
is undefined when denominator equates to zero. The critical point is:
b) 
when numerator equates to zero. That is:
This equation shows two critical points:
,
c) The critical points found in point b) and the existence of a discontinuity in point a) lead to the conclusion of the existence local minima and maxima. By plotting the function, it is evident that corresponds to a local maximum. (See Attachment)
d) By plotting the function, it is evident that corresponds to a local minimum. (See Attachment)
The solution exist for the given equation are
x=-2
and
x=11/3
a. 40 if you dont believe me just look at a 40 degree triangle then the pic
(2,4), (4,8), (3,6), (5,10) because they’re all ratios of 1:2
