Step-by-step explanation:</h2>
Graph B consists of a parabola that opens downward. If a parabola opens downward, the the coefficient of x will be negative.
<h2>More details:</h2>
There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
Because the radius is properly the same or the volume is the same
Well, for 4 I believe you must divide 2/4 by 100 to make it a decimal, then divide the decimal by the 5. :) Hopefully that is correct!
