Let $()$f$($t$)$ be the piecewise linear function with domain $080$t$8$ shown in the graph below $($which is determined by connecting the dots$).$ Define a function $()$A$($x$)$ with domain $080$x$8$ by

$()=0().$A$($x$)=0$xf$($t$)$dt$.$

Notice that $()$A$($x$)$ is the net area under the function $()$f$($t$)$ for $00$t$$x$.$ If you click on the graph below, a full$-$size picture of the graph will open in another window.

Find the following values of the function $()$

$(0)=$

$(1)=$

$(2)=$

$(3)=$

$(4)=$

$(5)=$

$(6)=$

$(7)=$

$(8)=$
