Math Problem Statement
The path of a punted football is given by the function f(x) = − 16 2025 x2 + 9 5 x + 1.5 where f(x) is the height (in feet) and x is the horizontal distance (in feet) from the point at which the ball is punted. (a) How high is the ball when it is punted?
Correct: Your answer is correct. ft
(b) What is the maximum height of the punt? (Round your answer to two decimal places.)
Incorrect: Your answer is incorrect. ft
(c) How long is the punt? (Round your answer to two decimal places.)
