Answer:
a) f(g(x)) =
=
= x
g(f(x)) =
=
= x
f and g are inverses
b) f(g(x)) = x + 3 + 3 = x + 6
g(f(x)) = x + 3 + 3 = x + 6
f and g are not inverses
Step-by-step explanation:
a)
f(g(x)) =
=
= x
g(f(x)) =
=
= x
Since f(g(x)) = g(f(x)) = x, then f and g are inverses
b)
f(g(x)) = x + 3 + 3 = x + 6
g(f(x)) = x + 3 + 3 = x + 6
Since f(g(x)) = g(f(x)) ≠ x, then f and g are not inverses
Umm... if in 2000 it was 1.40 and in 2007 it was 2.60, you subtract the two ie 2.60 -1.40 and you will get 1.2
Then, take 1.2 and divide it by 1.40 and then multiply by 100
hope you got it :))
Your product will be greater than 3 1/4 because anytime you multiply a fraction times a whole number less than 1 you get a fraction less than one and any time you multiply by a fraction and a whole number greater than 1 your answer is greater than 1
Hopefully this helped
