Answer:
When f(x) = 7, x is equal to 5.
Step-by-step explanation:
When looking at this graph, we are looking for where the line hits a point where y is equal to 7. That's because f(x) is essentially the same thing as y.
The point in which the graph hits y = 7 is (5, 7). This means the x value we need is 5.
104 = -16T2 + 729
16t^2 = 729 - 104 = 625
4t = +/-25
t = +/-6.25
Between 6.25 and 13.5 seconds after he jumps
I don’t know really but my guess is 62%
