(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 (-∞,∞)

I think you left out a part of your question !
Answer:
Step-by-step explanation:
2y = -4x + 8
y = -2x + 4
perp. 1/2
y - 2 = 1/2(x - 6)
y - 2 = 1/2x - 3
y = 1/2x - 1
Answer:
It would definitely be cheaper by Subway..
Step-by-step explanation:
Subway is 2.75 per person and taxi (given all variables) could be close to $20...however, the Subway takes much longer but is still the best bet. Especially if traffic is an issue
Line 6 subway•24m
US$3
Taxi•5m
US$16-US$20
