reate a MATLAB script to generate and plot the following equations on the interval $5<=$x$<=5$:

$(1)$ y $=-3$x$+2($Linear equation$)$

$(2)$ y $=$ x$^2-4$x$+5($Quadratic equation$)$

$(3)$ y$=-0\mathrm{.}5$x$^3+3$x$^2-$x$+4($Cubic equation$)$

Plot these equations on the same graph, label the axes appropriately, provide a title for the graph, use different line styles and colors for each curve, and include a legend to distinguish between the equations.
