Order the following graphs from widest to narrowest. y=-1/6x^2, y=1/2x^2, y=2/5x^2

Question

Algebra 1._

Answer 1

The negative is not related to the width. To figure this out, let's get common denominators. The LCD is 30.

1/6 = 5/30

1/2 = 15/30

2/5 = 12/30

The lower the denominator, the wider it will be

1/6 - widest

2/5 - second widest

1/2 - most narrow
