initial vertical velocity of 92 feet per second. The function h(t) is shown
below. Which of the following statement is TRUE? Select ALL that apply.

1. The potato was launched from the ground.

2. The flight is symmetric about the line t = 2.

3. The potato reaches a maximum height of about 3 ft

4. The potato is in the air during the interval 0
5. The potato reaches its maximum height after about 3 seconds in flight.

6. h(2)=h(5)

Answer 1

See below

Explanation:

Answer choices:

1. The potato was launched from the ground.

• False. 20 feet above the ground

2. The flight is symmetric about the line t = 2.

• False. Line of symmetry is t=3

3. The potato reaches a maximum height of about 3 ft

• False. Maximum height is about 150 ft

4. The potato is in the air during the interval 0

• Unclear. no interval given

5. The potato reaches its maximum height after about 3 seconds in flight.

• True

6. h(2)=h(5)

• False. h(2) = 140 ft, h(5) = 80 ft
