If f(x)=1/x and g(x)=x^2-4x. What two numbers are not in the domain of f o g?
statuscvo [17]

The composed fraction f \circ g means that the input of f(x) is the ouput of g(x).

So, the chain is

x \mapsto g(x) \mapsto f(g(x)) = f\circ g = \dfrac{1}{g(x)} = \dfrac{1}{x^2-4x}

The domain of f(x) is composed by all inputs which are not zero, otherwise we would have a zero denominator.

So, since f(x) doesn't accept 0 as an input, and we want to feed it with g(x), we conclude that g(x) can't be zero.

So, we have

f \circ g = f(g(x)) = f(x^2-4x) = \dfrac{1}{x^2-4x} \implies x^2-4x \neq 0

Since

x^2-4x = x(x-4)

we have

x^2-4x = 0 \iff x(x-4) = 0 \iff x=0 \lor x=4

Since these two points cases g(x) to vanish, they can't be accepted as inputs by f(x).
