Question

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)

y≤3


y≤74


y=
all real numbers

y=3

Answer 1

y = 3

The vertex gives the minimum height of the seat (the lowest point of the swing), which is 3 feet above the ground.
