The following chart depicts a $f(x).$ You are required to estimate its roots. Perform the iterations starting from the shown $x_1$ and $x_u,$ which are bracketing several potential roots $(a,b,c,$dots,$i).$ Solve it visually$/$graphically using a ruler $($when needed$)$ to identify which of these roots will be estimated by using:

$($a$)$ Bisection method

$($b

$)$ False Position method.
