A
Step-by-step explanation:
f(x) = 2x
f(-4) = 2(-4) = -8
So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
The second answer choice.
It would be 2/3 because you have to minus 2x on to the other side then you do-3 to -6 and -2x and you would get for your Y INTERCEPT would be 2/3
