Question

What does the second coordinate of the vertex of the quadratic function A(w) represent?

A. The minimum width that can be used for the fencing
B. The maximum area that can be enclosed by the fencing
C. The width that gives the maximum area
D. The length that gives the maximum area

Answer 1

The second coordinate of the vertex of a quadratic function represents the width that gives the maximum area.

Step-by-step explanation:

The second coordinate of the vertex of a quadratic function represents the width that gives the maximum area.

To find the second coordinate of the vertex, you can use the formula x = -b/2a, where a, b, and c are the coefficients of the quadratic function in the form ax^2 + bx + c.

For example, if you have the quadratic function A(w) = -3w^2 + 2w + 5, the second coordinate of the vertex can be found by substituting the values of a and b into the formula: x = -2/(2*(-3)) = 1/3.
