what parabolas is 2 units higher than y = 2x2 − 4x − 1, but has the same shape and opens in the same direction

OpenStudy (anonymous):

'2 units higher' means that the modified function will be the same except that y will be larger by 2, correct? The rewrite the given function that way: \[y = 2x ^{2} - 4x - 1 + 2\]

Usually one would simplify this by replacing -1 + 2 by +1.
