14. When fighter pilots train for dog-fighting, a “hard-deck” is usually established below which no competitive activity

can take place. The polynomial graph given shows Maverick’s altitude (y in 100s of ft) above and below this hard-deck during a 5-sec (x) interval.

a. What is the minimum possible degree polynomial that could form this graph? Why?

b. How many seconds (total) was Maverick below the hard-deck for these 5 seconds of exercise?

c. After how many seconds is Maverick 900 feet below the hard deck?

d. Given that the leading coefficient a = 100, determine the equation of the function in factored form. ( )
