F°g(x) = (3x-2)² -1
= 3x(3x-2)-2(3x-2) -1
= 9x² -6x-6x+2-1
=9x²-12x+1
Answer:
Step-by-step explanation:
<u>Given</u>
- Investment P₀ = $8300
- Interest rate r = 6.6%
- Compound = continuous
- Time t=14 years
- P = ?
<u>Formula for continuous compound interest:</u>
- P = P₀e
^rt, where e = 2.71828, constant used for continuous interest
- P = 8300*(2.71828)^(14*0.066)
- P = $20910.57 = $20911 rounded to the nearest dollar
The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).
The function is increasing on (-3,1).
No local or absolute minimum.
(1,4) is an absolute max.
