Answer:
OK so this may or may not help u ...
this can be taken as the straight line with equation
y = mx + c
here f(x) is taken to be y
the attached pic is the graph of this function
so I think the value of x before it explodes would be 18.875
- as in 18.875 seconds the rocket has reached its maximum height ( from 0 to 302)
and x represents the time
the time before it explodes = 18.875
and f(x) represents height so we see that the highest possible value of f(x) from the graph is 302
the height at which it explodes would be = 302
