Applications of Quadratic Functions
The Practical Range of the function is from 0 to the output value of the vertex The input value of the Vertex is the time it takes for the arrow to reach its highest point The input value of the horizontal intercept is the distance the arrow has traveled before it hits the ground The output value of the Vertical Intercept is the height of the arrow at time $\displaystyle {t}={0}$ The Practical Domain of the function is from 0 to the input value of the vertex

Applications of Quadratic Functions

The function $\displaystyle {h}{\left({t}\right)}=-{16}{t}^{{2}}+{80}{t}+{130}$ , where $\displaystyle {t}$ is time in seconds and $\displaystyle {h}{\left({t}\right)}$ is the height of the arrow in feet, models the height of an arrow shot into the sky as a function of time. Given that function, which of the following are true? Check all that apply.

The Practical Range of the function is from 0 to the output value of the vertex
The input value of the Vertex is the time it takes for the arrow to reach its highest point
The input value of the horizontal intercept is the distance the arrow has traveled before it hits the ground
The output value of the Vertical Intercept is the height of the arrow at time $\displaystyle {t}={0}$
The Practical Domain of the function is from 0 to the input value of the vertex
