Good luck!!!!
(fg)(x)= x³ - 7x² - 9x + 8
domain is (-∞,∞)
Given: f(x)= x-8, g(x)= x² +1x - 1
To find (fg)(x) we multiply f(x) and g(x)
(fg)(x) = f(x) * g(x)
(fg)(x)= (x-8) (x²+x-1)
(fg)(x)= x³ + x² - x - 8x² - 8x +8
(fg)(x)= x³ - 7x² - 9x + 8
we know, domain for all cubic function is set of all real numbers
domain is (-∞,∞)

Answer:
The answer is =A2*B2*C2
Step-by-step explanation:
1/4= 0.25 como un decimal
1 day = 24 hours
58 days = (24)(58) = 1392 hours
60 mins = 1 hour
30 mins = 30/60 hour = 1/2 hour
Total hours Keurig takes to complete a full rotation = 1392 + 15 + 1/2 = 1407(1/2) hours.
