Here is an example of how to create a plot of the function sin(x) for x running from -π to π, with an additional arrow starting from (2π,0) and ending at (3π,0) and a plot range from -π to 3π using the Wolfram Language:
Plot[Sin[x], {x, -Pi, Pi},
PlotRange->{{-Pi,3 Pi},{-1,1}},
Epilog -> {Arrow[{{2 Pi, 0}, {3 Pi, 0}}]}]
This will create a plot of the function Sin[x] for x running from -π to π. The Epilog option is used to add additional graphical elements to the plot, in this case an arrow is added to the plot by using Arrow[{{2 Pi, 0}, {3 Pi, 0}}]. This creates an arrow starting from point (2π,0) and ending at point (3π,0)
The PlotRange option is used to set the range of the x and y axis of the plot. In this case, the x-axis range is set to {-π,3π} and y-axis to {-1,1}.
The plot will show the sin(x) curve for x from -π to π, an arrow starting from (2π,0) and ending at (3π,0) and the range of x-axis from -π to 3π and y-axis from -1 to 1.
