in order to shift a graph "up"; we have to add a number to it; to determine the original place for it; subtract that number back out.

f(x) reflects over the x axis means it turns to f(x) add 4 means we get: f(x) + 4 f(x) + 4 = 4x^2 ; we can solve for f(x) now, subtract 4 f(x) = x^2 ; multiply by 1 f(x) = x^2
