Fill the blanks with $y$ $x=0$ vertical
$f(x)=b^{x}$ and $g(x)=\log_{b}x$ are inverse functions. Their graphs are reflections about the line $y=x.$ $b^{x}$ has a horizontal asymptote, the x-axis $(y=0)$. so $\log_{b}x$ has a vertical asymptote, the y-axis $(x=0)$ Fill the blanks with: $y$ $x=0$ vertical
