The quadratic function given is:

$y = -0.083(x - 6)^2 + 3$

This equation represents the jump height $y$ (in meters) of a kangaroo as a function of the horizontal distance $x$ (in meters).

This function is in vertex form $y = a(x - h)^2 + k$, where the vertex is at the point $(h, k)$. In this case:

• $h = 6$
• $k = 3$

Thus, the vertex of this function is at the point $(6, 3)$.

Interpretation of the Vertex:

The vertex $(6, 3)$ represents the maximum height of the kangaroo's jump. Specifically:

• The kangaroo reaches a maximum height of 3 meters.
• This maximum height occurs when the kangaroo is 6 meters horizontally from its starting point.

In practical terms, the vertex represents the peak of the jump. Since the parabola opens downward (indicated by the negative coefficient $-0.083$), the vertex is indeed the highest point of the jump.

Tip

In a quadratic function in vertex form $y = a(x - h)^2 + k$, the sign of $a$ determines whether the parabola opens upwards (positive) or downwards (negative).
