Transcribed Image Text:1 Detemine the real roof of f (x) = - 26+ 85x-91x + 44x3 - 8x4 + x5
al Using bisection to determine the root to ei = 10%. Employ initial guesses of a3=
0.5 and b = 1.0.
Perfom the same computation as in a) but use the false-position method and
Jerl = 0.2%.
2. Determine the real root of Inx = 0.7
a) Using three iterations of the bisection method. Employ initial guesses of a = 0.5
and b= 2.0.
b) Using three iterations of the false-position method with the same initial guesses as
a).
3. Determine the positive square root of 18 using false-posifion method to within Jeil :
0.5 %. Employ initial guesses of 4 and 5.
4. Find the positive real root of f(x) = x4- 8x3 - 35x2 + 450x - 1001 using the false-position
method and bisection method. Use inifial guesses of a = 4.5 and b = 6 and perform
five iterations. Compute both the true and approximate errors based on the fact that
the root is 5.60979. Use a plot to explain your results and perform the computation to
within es = 1.0%.
