Question

Order the group of parabolas from widest to narrowest

y = 1/4x 2, y = -1/2x 2, y = 3/2x 2

A.
y = 1/4x 2, y = 3/2x 2, y = -1/2x 2

B.
y = -1/2x 2, y = 1/4x 2, y = 3/2x 2

C.
y = 1/4x 2, y = -1/2x 2, y = 3/2x 2

D.
y = 3/2x 2, y = -1/2x 2, y = 1/4x 2

Answer 1

The answer is C. The smaller the value, the less stretch and more compressed the parabola is.
