Two different tennis instructors are using the same ball machine to help students practice returning lob shots.
1 answer:
Given thata the first instructor uses the function h to give the height of a tennis ball, in feet, when it is a horizontal distance of x feet away from the ball machine.
Now the second instructor places the ball machine on a 2-foot tall plateform. that means height of the machine is 2 feet more than the previous height of machine used by first instructor. We have to find the height g(x) for 2nd instructor which is just 2 feet more than previous height h(x).
Due to 2 feet more height, ball will achieve hieght 2 feet more than previous case.
So to find the answer, we will just add 2 into values of h(x) from first table.
Hence final answer is given by: (check attached picture)
