Let $f(x)=\sqrt{a x+1}$ And $g(x)=\ln (b x)$ For Positive Constants $a$ And $b$ Let

Short Answer

Let $f(x)=\sqrt{a x+1}$ and $g(x)=\ln (b x)$ for positive constants $a$ and $b$ . Let $h(x)=a x \ln \left(b^{2} x^{2}\right)+\ln \left(b^{2} x^{2}\right)$ . If $f(4)=2$ and $g(4)=3$ , what is $h(4) ?$
