• gcd requires numeric inputs.

Given the function h(x)={3x+10x<23x29x8x2\displaystyle {h}{\left({x}\right)}={\left\lbrace\begin{array}{cc} -{3}{x}+{10}&{x}<{2}\\{3}{x}^{{2}}-{9}{x}-{8}&{x}\geq{2}\end{array}\right.}
Calculate the following values:

h(1)=\displaystyle {h}{\left({1}\right)}= 
h(2)=\displaystyle {h}{\left({2}\right)}= 
h(9)=\displaystyle {h}{\left({9}\right)}= 
h(4)=\displaystyle {h}{\left(-{4}\right)}=
