Answer: (f·f)(0) = 4
(fof)(0) = -8
<u>Step-by-step explanation:</u>
f(x) = 3x - 2
(f·f)(x) = (3x - 2)(3x - 2)
= 9x² - 12x + 4
(f·f)(0) = 9(0)² - 12(0) + 4
= 4
(fof) = 3(3x - 2) - 2
= 9x - 8
(fof)(0) = 9(0) - 8
= -8

Step-by-step explanation:
Answer:
t=6
Step-by-step explanation:
ground height = 0
(are you sure your formula is correct? isn't it - 16t²?)
if h=16t² +64t+192 is true then
16t² +64t+192 = 0
t² + 4t + 12 = 0
t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2
There is no solution of t
if it is h= - 16t² +64t+192
0 =- 16t² + 64t + 192
t² - 4t - 12 = 0
(t + 2) (t -6) = 0
t should be positive
t = 6 sec
