Question

Select the correct answer.
If f(x) = (x+1)-¹ and g(x)
= x^-2, what is the domain of f(x) = g(x)?

Answer 1

Explanation:

`f(x)=g(x) \implies (1)/(x+1)=(1)/(x^(2))`

This means the denominators cannot equal to (because then the fractions would be undefined) so the domain is
`x \in \mathbb{R} -\{-1,0\}`
