Question

Which of the quadratic functions has the narrowest graph?
A) y = 1/3x^2
B) y = 1/8x^2
C) y = -2x^2
D) y = -3x^2

Answer 1

Answer:

y = -3x² has the narrowest graph

Step-by-step explanation:

D)  y = -3x² has the narrowest graph.  That coefficient "3" stretches the graph of x² vertically.

On the other hand, B) has the widest graph.
