Answer:
Just how much dollars?
Step-by-step explanation:
If a whole number, then rounded would be the exact same thing. If a decimal, example, $12.28 then round it to $12.30. Hope this helps!
Yes, its also an integer, rational and real number
Answer:
From greatest to least it would be: v,w,x,z
Step-by-step explanation:
(f+g)(x) = 2x - 1 + x^2 + 7 = x^2 + 2x + 6
(f-g)(x) = 2x - 1 - x^2 - 7 = -x^2 + 2x - 8
(f*g)(x) = (2x - 1)(x^2 - 7) = 2x^3 - 14x - x^2 + 7 = 2x^3 - x^2 - 14x + 7
(f/g)(x) = (2x - 1)/(x^2 - 7) - No simplification
f(g(-8)) = 2((-8)^2) - 7) - 1
= 2(64 - 7) -1
= 2(57) - 1 = 114 - 1 = 113
g(f(1)) = (2(1) - 1)^2 - 7
= (2 - 1)^2 - 7
= 1^2 - 7 = 1 - 7 = -6
