Question: How can I plot a function from higher to lower values?

My question deals with plotting a function, namely, x(t), from lower to higher values of t.

To this aim, I solved a simple differential equation with given initial conditions and then plotted for the result.

As it is seen, maple starts from lower values of t to higher ones. However, is there a command through which I can reverse the plotting procedure?  

From the attached file, "A question on plotting", we see that the slope of the curve at t=2 is positive when we observe it from "left to right". However, this slope is negative once we start plotting from "right to left".

Is there any command with which I can start plotting from right to left? or change of axis origin?

I would appreciate for your kind help and support.

My best regards
