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

y$=2$x$+3$

y$=$x$^24$x$+4$

y$=-$x$^3+3$x$^2-2$x$+5$

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.
