Let the x be the number
So,
(4(x+0.5)-2)/2=48
So,
x=24 is the number.

Step-by-step explanation:
Larger the value of '' a '' makes the parabola narrow.
A positive value of '' a '' which is close to 0 makes the parabola wide.
<em><u>To find the widest graph , find the smallest </u></em><em><u>a</u></em><em><u>. (or </u></em><em><u>a</u></em><em><u> closest to zero)</u></em>
option 1

option 2

option 3

option 4

Positive and negative value of ' a ' decides the direction the parabola opens.
But we have to find the widest parabola irrespective of the direction.
So we will find the smallest ' a '


First you have to distribute:
4(2) + 4(3)
8+12
