”, moved the cursor to the right of the top after “Right Bound? To get the root, push 2 TRACE (CALC), and then push 2 for ZERO (or move cursor down to ZERO). ” Using the cursors, move the cursor anywhere to the left of the zero (where the graph hits the \(x\)-axis) and hit ENTER. Audrey throws a ball in the air, and the path the ball makes is modeled by the parabola \(y-8=-0.018\), measured in feet.

Typically a reasonable range for these types of problems is The profit from selling local ballet tickets depends on the ticket price.

Using past receipts, we find that the profit can be modeled by the function \(p=-15 600x 60\), where \(x\) is the price of each ticket.

Note also that we will discuss Optimization Problems using Calculus in the Optimization section here.

where \(t\) is the time in seconds, and \(h\) is the height of the ball.
