Let's go for a ride on the roller
coaster, which is
seconds long. The rollercoaster begins at
feet above ground. After seconds we will reach the maximum height of
feet. Therefore, the values for the domain of this rollercoaster are
and the range is
We will be moving
slow during the intervals of
because we will be going
hill, which means these are intervals of
We
will be moving very fast during the intervals of

In function
notation, f(12) =
which means at
seconds the rollercoaster is
