Show that \(f\) and \(g\) are inverses of each other by verifying that \(f[g(x)]=x\) and \(g[f(x)]=x\). $$ f(x)=\frac{1}{x} ; \quad g(x)=\frac{1}{x} $$
You are given the graph of a function \(f .\) Determine whether \(f\) is one-to- one.
Show that the vertex of the parabola \(f(x)=a x^{2}+b x+c\) where \(a \neq 0\), is \((-b /(2 a), f(-b /(2 a)))\).
Find the inverse of \(f .\) Then sketch the graphs of \(f\) and \(f^{-1}\) on the same set of axes. $$ f(x)=x^{3 / 5}+1 $$
Find the inverse of \(f .\) Then use a graphing utility to plot the graphs of \(f\) and \(f^{-1}\) using the same viewing window. $$ f(x)=\frac{x}{\sqrt{x^{2}+1}}, \quad-1 \leq x \leq 1 $$
