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

y = -3x² has the narrowest graph

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.
