Uh I did not learn this yet but I think The answer is 2,4
Indicated here when h(t) = 0, we are to find for the time where the football has reached a certain height.
Then, the values of t would be -0.2 and 2.7.
Since we are to look for the time, it is impossible for us to have an answer that has a negative value. So based from our answer, the solution that we will eliminate is the -0.2 one. Since its value is negative.
So, the correct value would be the 2.7 sec. one.
E' (-2, 2) , J'(-1, -2) , R'(-3,-3) , S'(-5, -2)
