Question
Given the function $g$, prove that $g$ is not one-to-one using the definition of a one-to-one function on p. 390 .$g(x)=1-x^{2}$
Step 1
A function \( g \) is one-to-one (injective) if and only if for every pair of distinct elements \( a \) and \( b \) in the domain of \( g \), \( g(a) \neq g(b) \). Show more…
