Q$1)(20$ pts$)$ Asymptotic analysis: visually

For each of the following plots, provide a tight big$-$O bound, a tight big$-\backslash (\backslash$Omega $\backslash )$ bound, and a big$-\backslash (\backslash$Theta $\backslash )$ bound. You do not need to show your work; just list the bounds. If a particular bound doesn't exist for a given plot, briefly explain why. Each provided bound should either be a constant or a simple polynomial $($e$.$g$.$ O $(1),$ O $($n$),$ O $($n$2)...).$

Assume that the plotted functions continue to follow the same trend shown in the plots as x increases.
