Determine The Real Roots Of X 05×2

Determine the real roots of ƒ(x) = – 0.5×2 + 2.5x + 4.5:

(a) Graphically.

(b) Using the quadratic formula.

(c) Using the iteration of the bisection method to determine the highest root. Employ initial guesses of xl = 5 and xu = 10. Compute the estimated error εa and the true error εt after each iteration.
