Problem $2$:

Determine the root $($highest positive$)$ of

$f(x)=-0\mathrm{.}6**x^2+2\mathrm{.}4**x+5$

a$)$ Perform $3$ iterations by hand of the bisection method, using initial guesses $x=5,$ and $xu=10.$

b$)$ Write your own MATLAB function to validate your results and plot the error.

c$)$ Compare the results of question $"a"$ to the results of question $"$b$",$ What is your conclusion?

Note: Remember to compute the error Epsilon$-$a $($given in the slides$)$ after cach iteration.
