You use the first formula. You plug in the values to get A=400(1+(0.05/1))^6. You should get approximately $536.04. I used 0.05 because you need to change the percent to a decimal, and 1 for n because it is compounded annually, meaning once a year.
Answer:
only G is even
it's obvious that g is even. g(x)= |x|
for ...
it's a quadratic equation with roots -1 and 4,
thus the equation will be
(if you have roots of a quadratic equation, the equation is
or
now, put the point (0,4)
so the equation is
now if you put
you get
which is not the same.
hence
10.8 or 10.9
