Answer:
The ball is 7 feet above the ground 2 seconds after it is thrown.
Step-by-step explanation:
As per the given statement, we are given a graph of function [tex]f(x)[/tex] where 'x' is time (in seconds) in the current scenario.
Time is plotted on x axis and height of football is plotted on y axis.
[tex]f(x)[/tex] is the height of football according to change in time.
Following are the few things that can be observed from the given curve:
1. Initial Height of football is ~4.8 feet i.e. at 0 seconds of time.
2. Football reaches a maximum height of ~7.2 feet at 1.5 seconds.
3. After 1.5 seconds, the height of football starts decreasing.
Here f(2) means, the height of ball at 2 seconds of time.
It is clearly visible from the given graph that height is 7 feet at 2 seconds.
Please refer to the attached answer image. Height at 2 seconds is marked as point P.
Hence, The ball is 7 feet above the ground 2 seconds after it is thrown.
