Question

Which of the following quadratic functions has the widest graph?
A) Y=1/3x^2
B) Y=-4/5x^2
C) Y=-4x^2
D) Y=0.3x^2

Answer 1

If I am correct, the answer should be D. If you need further explanation, I can supply you with that as well.

Answer 2

Using quadratic function concepts, it is found that the wider is given by:

D. $Y = 0.3x^2$

The lower the absolute value of the number that multiplies $x^2$, the wider the parabola is.

• In item A, this value is $\frac{1}{3} = 0.333$
• In item B, this value is $|-\frac{4}{5}| = |-0.8| = 0.8$
• In item C, this value is $|-4| = 4$.
• In item D, this value is $|0.3| = 0.3$

The lowest value is in item D, thus it is the wider parabola.
