How can I iterate a function up to a certain integer and plot the resulting functions to a single graph [closed]

Firstly I'm sorry if this has been asked before, but I couldn't find what I was looking for.

Say I have a function:

f[x, a] := x^2 + a


Is it possible to plot a single graph of all f[x, a] against x with a taking integer values up to some number N and x between -10 and 10?

Plot[Table[x^2 + a, {a, 0, 5}],
