Card 1 of 23
In f(g(x))f(g(x))f(g(x)), which function acts first?
A
Apply ggg first.
B
The domain of f−1f^{-1}f−1 is the range of fff, while the range of f−1f^{-1}f−1 is the domain of fff.
C
x≤3x\leq 3x≤3
D
The graphs of y=f(x)y=f(x)y=f(x) and y=f−1(x)y=f^{-1}(x)y=f−1(x) are reflections in y=xy=xy=x, so a vertical asymptote becomes a horizontal asymptote.
