Determine the root of f(x) = 2x3 - 11.7x% + 17.7x - 5 using secant method (x.1 = 2, xo = 2.5). Use at least six decimal places. First iteration, at x1 =2 & xo = 2.5, Calculate f(x.1) = Calculate f(xo) = Calculate x; = Calculate g, = Second iteration, at xo=2.5 & x; = Calculate f(x1) = Calculate x; = Calculate , = Continue calculation to fill up the following table Iteration Xi-1 f(xi.1) Xi f(xi) , 0 2 2.5 - 1 2 3 Root is
