Hiding parts of a graph

I have been trying to plot several variations of a parabola-like function
on one graph.  The problem that I am encountering is that I only want part
of each function to appear on the graph.  I have tried the following
example:

list = Table[Plot[x^2 + n, {x, n, 10}], {n, 0, 10, 1}]
Show[list]

That example works and graphs each function starting at the desired point.
The problem I am having is that I do not want equal intervals of n.  I
have a list of values that I need to use as my n value.  I have tried the
following with no success:

(This is an extremely simplified example of the function and n values that
I need to graph)

a={1,3,5.6,99,101.01}
Plot[Evaluate[ReplaceAll[x^2 + n, n->a]],{x, n, 10}] -- I have also tried
this with {x, a, 10}

If there are any ideas on how I might go about doing this please let me
know.

Thanks,
Amy Sommer
