Q$.1$ Please solve the question with matlab code. Find the root of the function $f(x)=x^2-4e^{-x}-3$ on the interval $1,4$ with the error tolerance $|f(x)|{10}^{-5}$ with the initial points $x_0=1\mathrm{.}6,x_1=1\mathrm{.}7,x_2=1\mathrm{.}8($if only one initial condition is required, take only $x_0=1\mathrm{.}6,$ for two initials, take $x_0=1\mathrm{.}6,x_1=1\mathrm{.}7,$ for three initials, take $x_0=1\mathrm{.}6,x_1=1\mathrm{.}7,x_2=1\mathrm{.}8)$ by using below methods. Create a table to compare convergence rates, iteration numbers and CPU times of the methods.

a$.$ Newton's method

b$.$ Secant Method

c$.$ M$$ller$\text{'}$s method

d$.$ Regula Fals$1$ Method

e$.$ Fix$-$Point Method
