Answer: Bub I dont Know How I am Stuck On It Too
Step-by-step explanation:
ARGH
Answer:
Step-by-step explanation:
Given that there is a function of x,

Let us find first and second derivative for f(x)

When f'(x) =0 we have tanx = 1 and hence
a) f'(x) >0 for I and III quadrant
Hence increasing in 
and decreasing in 


Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1

are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)
Answer:
x=8.16
Step-by-step explanation:
x=the money before
2x=doubled
3x=24.50
x=8.16
63 divided by 9 is 7, so -7+7 is 0
Hope this helped
