You need to make the function depend on 'a' as well as 'x'. The attached shows how to do it using a slider to vary the value of 'a' (though you can set 'a' any way you want).

Thanks , very much . this was helpful

but , Is there another way (other than the slider method) I can plot the function without specifying any values of a

OR just specifying an interval like a=[0, infinity]

You can't really expect Mathcad to plot without knowing one or more values of 'a'!

However, you could plot a surface using a 3d plot for a specified range of values of 'a' and 'x'.

For example:
