2B.) Apply Newton’s method to find the root(s) of the function: f(x) = (8)x 3 – (8)x 2 – (8)x + 1 = 0. The answers should be given in a range from a = -2 to b = +2. Your iteration should stop when it reaches the change in sign (polarity) in your computation. The starting point should be (a) 0.3 and (b) 0.7. Choose your own increment value. 2. (a) when x = 0.3; xstarts = __________ xends = __________ f(xstarts) = _________ f(xends) = _________ (b) when x = 0.7 xstarts = __________ xends = __________ f(xstarts) = __________ f(xends) = __________
