Spring ACPR: Parametric Equations

 Using the parameter  $t=\ \frac{x}{3}-1$, which pair of parametric equations represents   $y=4+x^2$  ?

•  $x=3t+1$

   $y=9t^2+5$

•  $x=3t+1$

   $y=9t^2+6t+5$

•  $x=3t+3$

   $y=9t^2+13$

•  $x=3t+3$

   $y=9t^2+18t+13$

Hint: Figure out the necessary t-value and then worry about the height.

• The ball falls short of the fence and lands in the outfield.

• The ball hits about halfway up the fence.

• The ball hits the top of the fence.

• The ball clears the fence for a home run.
