determine the following composition and state the domain in interval notation.
f(x) = (√x+2) , g(x) = x / x-1
a) (fog)(x)
f(x) = (√x+2) , g(x) = x / x-1
a) (fog)(x)
-
f(x) = (√x+2) , g(x) = x / x-1
a) (fog)(x) = f(g(x)) = √(g(x))+ 2 ===> √(x / x-1)+ 2
(b) domain, x > 1 which is (1,oo)
a) (fog)(x) = f(g(x)) = √(g(x))+ 2 ===> √(x / x-1)+ 2
(b) domain, x > 1 which is (1,oo)
