How do I define a function that, when given a list of parameters, plots a family of functions?

Question

So far I've got this:

draw[a_, b_] := Plot[{f[a, b[[1]], x], f[a, b[[2]], x]}, {x, 0, 5}]

The function draw will be used like this:

draw[10, {4, 7}]

The example is written for the case with two elements in the list that is the second argument. How do I do it when the second argument is a list with any number of elements?

It would help us to help you if you edited your question to include an example of kind of function you would give for f. — m_goldberg, Jan 04 '13 at 02:07

You can use Map:

draw[a_, b_] := Plot[Evaluate[f[a, #, x] & /@ b], {x, 0, 5}]
