Answer:
Option 3.
Step-by-step explanation:
The given function is

where, h(t) is the height of a small rock falling from the top of a 124-ft-tall building and t is the time in seconds.
It is a downward parabola.
Equate the function equal to 0, to find the time at which the rock touch the ground.

If
, the according to the quadratic formula

Using quadratic formula, we get



Time cannot be negative. So, the rock remain in the air in the interval 0 < t < 2.
Therefore, the correct option is 3.
You want to isolate the variable using the division property of inequality:
3x / 3 < -6 / 3 = x < -2. The sign of the inequality stays the same since you did not change the order of the inequality nor did you divide by a negative number on both sides. Hopefully this helps!
A quadrilateral I believe.
