Analyzing Functional Relationships

Question 1

The path of a basketball during a free throw can be modeled with the function shown, where x is time, in tenths of a second, since releasing the ball and f(x) represents height in feet. Which statements correctly describe this function?

Revolt · Accepted Answer

The basketball reaches a maximum height of 7 feet.; The height of the ball at time 0 is 6 feet.; The graph is symmetric about the line x = 5.5.

Question 2

The table shows the amount of a radioactive sample that remains after a certain number of days. Use the data in the table to describe the relationship between the number of milligrams remaining and days.
