What does requirment $($vi$)$ means

$9.)$ Sketch the graph of a function $f$ which satisfies all the following conditions:

$($i$)$ The domain of $f$ is $[0,+).$

$($ii$)f$ is continuous on $[0,3)$ and on $[3,+).$

$($iii$)\underset{x{0}^{+}}{lim}\frac{f(x)-2}{x}=1.$

$($iv$)f^{\text{'}}(x)>0$ for every xin$(0,2)(3,4)(4,+).$

$($v$)\underset{x{3}^{-}}{lim}f(x)=-$

$($vi$)\underset{x4}{lim}\frac{f(x)-1}{x-4}=0.$

$($vii$)f^{\text{'}}(x)<mn>0</mn>$ for every xin$(2,3).$

$($viii$)f^{\text{'}\text{'}}(x)<mn>0</mn>$ for every xin$(0,3)(3,4).$

$($ix$)f^{\text{'}\text{'}}(x)>0$ for every xin$(4,+).$

$($x$)\underset{x+}{lim}(f(x)-x)=-5$
