Here is it not sure if you will spot it

8.75 m

Step-by-step explanation:

Given ordered pairs:  (0, 0) (1, 16) (2, 20) (3, 15.5) (4, 0)

From inspection, we can see that the difference in the x-values is constant (they increase by 1 each time), yet the difference in the y-values is not constant.  Therefore, the relation is not linear.

As the y-values increase from 0 to 20 and then decrease back to 0, the curve is likely to be a parabola opening downwards.

The x-intercepts are at x = 0 and x = 4, so this suggests that the axis of symmetry is x = 2, and so the vertex is (2, 20).

Creating an equation using the x-intercepts:

 where is some constant

Creating an equation using the vertex form:

Equating constants to determine a:

Therefore, equation of best fit:

When x = 0.5:

Therefore, an estimate for the height of the rocket 0.5 s after it's launched is 8.75 m

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
