Suppose a ball thrown from a building follows the trajectory below. The person tosses the ball from the point (0,8) and the ball lands on the ground at point (1.86, 0). What is the applied domain of the projectile? https://gls.agilix.com/Resz/~Ey6YBAAAAAQ_377KXjdipA.ufkxl4nREqUvV6Vw64RtsC/26618227,11A/Assets/Image%20A.PNG {x | 0 ≤ x} {x | 0 ≤ x ≤ 1.86} {x | x ≤ 1.86} There are no restrictions on the applied domain.

    hint: practical domain = portion of the parabola in the first quadrant

    you had it right the first time it's {x | 0 ≤ x ≤ 1.86}

    x cannot be less than 0. it's not practical or possible to go back in time
