The graph of y = 5x2 is narrower than and opens in the same direction aswider than and opens in the same direction asnarrower than and opens in the opposite direction ofwider than and opens in the opposite direction of the graph of y = x2.

In y = ax², a positive coefficient means the parabola opens upward, the same direction as y = x². Since |5| is greater than 1, y = 5x² is narrower than y = x². Therefore, the correct choice is “narrower than and opens in the same direction as.”
