<PRE><B>Question 305313</B>
f(x)= -0.01x^2+0.7x+6.1 in which x is the shot&#39;s horizontal distance, in feet, and f(x) is its height, in feet. Use the function to determine the shot&#39;s maximum distance. Use a calculator and round to the nearest tenth of a foot.&quot;
-------------
I graphed the function and found its maximum at x = 35, y = 18.35
---
Another way to find the max is:
x = -b/(2a) = -0.7/(2(-.01) = 35
---
Then height = f(35) = 18.35
