Question

jeremiah kicks a football. the graph below shows the height of the football h in foot after t seconds.
answer attempt 1 out of 2
the x - coordinate (or t - coordinate) of the vertex is
and represents
the y - coordinate (or h - coordinate) of the vertex is
and represents

Explanation:

Step1: Identify the vertex coordinates

The vertex of the parabola is given as \((1.4, 31.36)\). The \(x\)-coordinate (or \(t\)-coordinate) of the vertex is the first value in the ordered pair.
So, the \(t\)-coordinate of the vertex is \(1.4\). This represents the time (in seconds) when the football reaches its maximum height.

Step2: Identify the y-coordinate of the vertex

The \(y\)-coordinate (or \(h\)-coordinate) of the vertex is the second value in the ordered pair \((1.4, 31.36)\).
So, the \(h\)-coordinate of the vertex is \(31.36\). This represents the maximum height (in feet) of the football.

Answer:

The \(x\)-coordinate (or \(t\)-coordinate) of the vertex is \(\boldsymbol{1.4}\) and represents the time (in seconds) when the football reaches its maximum height.
The \(y\)-coordinate (or \(h\)-coordinate) of the vertex is \(\boldsymbol{31.36}\) and represents the maximum height (in feet) of the football.
