Answer:

Step-by-step explanation:
Because this quadratic equation would have the curve-down form of:

where a and b are positive coefficient.
If we let the peak (250 ft) of the curve be at x = 0. Then


Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have



Therefore, the model quadratic equation of our path would be

Step-by-step explanation:
Plug x in :
-8(7-3) = -32
Distribute :
-56 - (-24) = -32
Subtract :
-32 = -32
2x+3-5.32=68.82
2x= 71.14
x=35.57
