Match each quadratic expression that is written as a product with an equivalent expression that is expanded.

Select all expressions that are equivalent to .

Tyler drew a diagram to expand .

1. Explain Tyler’s mistake.
2. What is the correct expanded form of ?

Explain why the values of the exponential expression will eventually overtake the values of the quadratic expression .

A baseball travels meters seconds after being dropped from the top of a building. The distance traveled by the baseball can be modeled by the equation .

Which graph could represent this situation? Explain how you know.

Consider a function, , defined by  . Explain why negative values are not included in the range of .

Based on past concerts, a band predicts selling concert tickets when each ticket is sold at dollars.

1. Complete the table to find out how many concert tickets the band expects to sell and what revenues it expects to receive at the given ticket prices.

   ticket price (dollars)	number of tickets	revenue (dollars)
   10
   15
   20
   30
   35
   45
   50
   60

2. In this model, at what ticket prices will the band earn no revenue at all?
3. At what ticket prices should the band sell the tickets if it must earn at least 8,000 dollars in revenue to break even (to not lose money) on a given concert. Explain how you know.
