14. A volleyball is served from a height of 6 feet with an initial velocity of 33 feet per second.

The situation is modeled using the function h=−6t2+33t+6
, where h is the height in feet and t is the time in seconds.

Use the function to calculate the h(x) values in the table below.

To calculate the height \( h \) of the volleyball at different times \( t \) using the function \( h(t) = -6t^2 + 33t + 6 \), we'll substitute the values of \( t \) into the function.

  1. For \( t = 0 \): \[ h(0) = -6(0)^2 + 33(0) + 6 = 6 \]

  2. For \( t = 2 \): \[ h(2) = -6(2)^2 + 33(2) + 6 \] \[ = -6(4) + 66 + 6 \] \[ = -24 + 66 + 6 = 48 \]

  3. For \( t = 4 \): \[ h(4) = -6(4)^2 + 33(4) + 6 \] \[ = -6(16) + 132 + 6 \] \[ = -96 + 132 + 6 = 42 \]

Now, we can fill in the table:

\[ \begin{array}{|c|c|} \hline x & h(x) \ \hline 0 & 6 \ 2 & 48 \ 4 & 42 \ \hline \end{array} \]

So the values are:

  • \( h(0) = 6 \)
  • \( h(2) = 48 \)
  • \( h(4) = 42 \)
