<PRE><B>Question 1047916</B>
Find the greatest value of each function.
f(x) = -x^2-3x
------
The maximum value of y occurs when x = -b/(2a)
------
In your problem a = -1, b = -3
------
Max occurs when x = 3/(2*-1) = -3/2
------
The maximum value of y = f(-3/2) = -(-3/2)^2 - 3(-3/2) = -(9/4) + (18/4)
= (9/4)
