Printable in convenient PDF format.Mar 20, 2023 · The correct answer is -4 and -3 because the graph of a quadratic function intersects the x-axis at the x-coordinate(s) of its roots. Since the question states that one root lies between -4 and -3, it means that the graph intersects the x-axis between these two consecutive integers. What does the second coordinate of the vertex of the quadratic function. A(w), represent? the minimum width that can be used for the fencing. the maximum area that can be enclosed by the fencing. the width that gives the maximum area. the length that gives the maximum area.
