Which graph correctly shows the inequality y≥−x2−4x−8 ?
The table shows the price of movie tickets for certain years.
Find the linear regression equation.
Round to the nearest hundredths.
y = .22x + 5.77
y = -.22x - 5.77
y = .22x - 5.77
y = -.22x + 5.77

A coin is thrown off the top of a building which is 305 feet from the ground. The height, h, of the coin is recorded after each second, t, in the table.
Write a quadratic regression equation for the path of the coin.
y = -16x2 + 78 x + 305
y = 16x2 - 78 x + 305
y = 16x2 + 78 x + 305
y = -16x2 + 78 x - 305
