Don't make the mistake of saying that the new function is up above the given function. f(x) + 3 is not above f(x) = x. f(x) + 3 is below f(x).
The answer is B <<<<<=====
y + 3 = x is the way you can think of it. y = x - 3 is what it is. If you have a graphing calculator, graph it. You want to see that it is below f(x) = x or going down.
