A projectile is shot into the air. The altitude of the projectile after seconds is modeled by the function graphed. Time is measured in seconds and altitude ℎ() is measured in feet. The table models the flight of the projectile.

Which of these statements is true?
A.
ℎ(4) < ℎ(20)
B.
The flight is symmetric about the line = 10.
C.
The projectile will hit the ground at some value of less than 24.
D.
f 0 < < 12, then ℎ(12 − ) = ℎ(12 + ).

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

Will gve pints stars and brainliest
