##### Try this ACT math practice question on interpreting terms in a parabolic relationship.

An object thrown directly upward is at a height of $h$ feet after $t$ seconds, where $h = -16t^2 + 12t + 24$. The number $24$ in this equation represents which of the following?

- $\quad$ The highest distance the ball is from the ground.
- $\quad$ The distance the ball is from the ground when it is thrown upward.
- $\quad$ The number of seconds the ball will take to reach the highest point.
- $\quad$ The number of seconds the ball will take to reach the ground.
- $\quad$ The velocity of the ball when it is thrown.
