Determine The Real Root Of X 25

Determine the real root of ƒ(x) = – 25 + 82x – 90×2 + 44×3 – 8×4 + 0.7×5:
(a) Graphically.
(b) Using bisection to determine the root to εs = 10%. Employ initial guesses of xt = 0.5 and xu = 1.0
(c) Perform the same computation as in (b) but use the false-position method and εs = 0.2 %.
