The parent function for an exponential function \(\displaystyle{y}={a}{b}^{{2}}\) is \(\displaystyle{y}={b}^{{2}}\) so the parent function of f is: \(\displaystyle{p}{\left({x}\right)}={2}^{{x}}\)
The exponential function \(\displaystyle{y}={a}{b}^{{2}}\) has a horizontal asymptote of \(y=0\). Since both p and f are of this form, then their asymptotes are both: \(y=0\)
