$1($n$).$Create MATLAB code to generate and plot three different mathematical functions on the same graph within the range $[4,4].$ Plot these curves using different line styles, colors, and markers. Include appropriate labels for the axes, a title for the plot, and a legend that distinguishes between the three curves.

Functions to plot:

$1.$f$($x$)=$sin$($x$)$

$2.$g$($x$)=$x$^33$x

$3.$ h$($x$)=1/(1+$e$^($x$))$

Your MATLAB code should:

Generate an array of x values using linspace.

Calculate the corresponding y values for each function.

Plot these functions on the same graph using different line styles, colors, and markers.

Include labels for the x and y axes, a title for the plot, and a legend to differentiate between the three curves.

Please write the MATLAB code that accomplishes this task.
