Algebra: Concepts and Connections EOC Review 3

An eagle begins its descent from a height of 20 feet above the ground. With each passing minute, the eagle descends 4 feet as it approaches its prey. This relationship can be represented by f(t) = −4t + 20, where f(t) represents the eagle’s height above the ground (in feet) and t represents the time (in Seconds). Which of the following statements are true?

Groups:

(a) True

,

(b) False

• The eagle descends 4 feet every second.

• The y-intercept of the graph is 20 representing the eagles’ initial height.

• The slope of the graph represents the rate of the eagle’s ascent.

• If the eagle hasn’t started its descent, its height is 20 feet above the ground.

• After 5 minutes, the eagle will be at a height of 0 feet.

• 20 representing the time it took for the eagle to reach the ground.
