Because there is 4 cups in a quart, we can turn 5 1/2 or 5.5 quarts into 22 cups:
5 1/2 or 5.5
( 5 x 4) + (0.5 x 4) = 22
Since we need to find how many cups were used, that is x. Because 22 cups is the total amount of cups and 4 is the amount remaining then the equation would look like this:
<u><em>A </em></u><u><em>quadratic function </em></u><u><em>is a second degree polynomial function. The general form of a quadratic function is this: f (x) = ax2 + bx + c, where a, b, and c are real numbers, and a≠ 0.</em></u>
