If a baseball reaches a maximum height of 130 feet, what does this indicate about the quadratic function modeling its height over time?

The statement that the vertex represents the maximum height is correct because, in the context of a quadratic function, the vertex is the point at which the function reaches its highest or lowest value, depending on its orientation. For a parabola that opens downward, which is the case when modeling the height of a projectile like a baseball, the vertex corresponds to the maximum height of the object.

In this specific scenario where the baseball reaches a maximum height of 130 feet, the vertex of the quadratic function will have a y-coordinate of 130. This vertex point is crucial as it indicates the peak height the baseball attains during its flight, thus reflecting the motion and parabolic trajectory of the baseball as it travels up and then down.

The other options do not accurately describe the relationship between the vertex and the maximum height in this context. For instance, the intercept does not determine the maximum height but rather indicates where the function crosses the axes, and a quadratic function is not linear as it follows a parabolic path, suggesting its shape is distinctly different from a straight line. Additionally, the height of the baseball is not constant, as it varies with time during its flight, peaking at the vertex before descending.
