Question

Which equation will produce the widest parabola when graphed?
A. y= 2x^2
B. y= -6x^2
C. y= -0.6x^2
D. y= 0.2x^2

Answer 1

b

Answer 2

To determine the steepness of a parabola, you just need to look at the coefficient before (x).

The higher the absolute value of the coefficient, the steeper it is.

Wouldn't you agree 2(x^2) would give you a bigger y-value than 0.2(x^2), and thus 0.2(x^2) would be wider.

Looking at all the answers, isn't the smallest absolute value come from 0.2(x^2)?

So the answer must be D

Answer 3

i thought the question was asking which one produces the one that is open more - so therefore 6x is greater than 2x
