The inverse of the function $y=\frac{10^x-10^{-x}}{10^x+10^{-x}}+1$ is $x=$

If $f(x)=\tan \left(\frac{\pi}{\sqrt{x+1}+4}\right)$ is a real valued function, then the range of $f$ is

If $\frac{x^3+3}{(x-3)^3}=a+\frac{b}{x-3}+\frac{c}{(x-3)^2}+\frac{d}{(x-3)^3}$, then $(a+d)-(b+c)=$

$f(x)=a x^{2}+b x+c$ is an even function and

$g(x)=p x^{3}+q x^{2}+r x$ is an odd function.

If $h(x)=f(x)+g(x)$ and $h(-2)=0$, then $8 p+4 q+2 r=$
