Which of the quadratic functions has the narrowest graph? Y = 1/6x^2, y = 2x^2, y = - x^2, y = 1/8x^2

Y = ax^2

If the absolute value of a is <1 the graph is wider than when a = 1

If the absolute value of a is >1 the graph is narrow than when a = 1

The only function that fits that description is

y = 2x^2

B <<< answer.
