Consider the following table:

$\backslash$table$[[x,0,2,4,6,8,10],[f(x),53,52,49,43,30,3]]$

$($a$)$ Use this data and a left$-$endpoint Riemann sum to estimate the integral:

${\displaystyle \underset{0}{\overset{10}{}}}f(x)dx$~~

$($b$)$ Use this data and a right$-$endpoint Riemann sum to estimate the integral:

${\displaystyle \underset{0}{\overset{10}{}}}f(x)dx$~~
