The path of a circus performer shot from a cannon can be described by the equation hlx) = -2X2 + 8x + 10, where h(x) is the height of the performer and x is the number of
seconds that have passed since the cannon was fired. Which of the following is the
extremum of the function?

22

Step-by-step explanation:

the answer is 22

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
