The seat on a swing set sits 3 feet off the ground. The chains that are attached to the seat are 74 inches long. Suppose you were to swing: the path of the swing forms a parabola. Interpret the y-value of the vertex, in terms of the context.(1 point) Responses y= all real numbers y equals all real numbers y≤74 y less-than-or-equal-to 74 y≤3 y less-than-or-equal-to 3 y=3

In the context of the swing set, the vertex of the parabola represents the maximum height of the swing seat. Since the seat is 3 feet off the ground, the vertex would correspond to this height.
Therefore, the correct interpretation of the y-value of the vertex in this context is:
y = 3 (the maximum height of the swing seat above the ground).
