<PRE><B>Question 466981</B>
Find the domain and range of y = x^2  +3x -2?
-------------
Domain: All Real Numbers (ARN)
-----
Since the vertex occurs at x = -b/(2a) = -3/(2) = -3/2
and f(-3/2) = (3/2)^2+3(-3/2)-2 = 9/4 - 18/4 - 8/4 = -17/4,
Range is ARN &gt;= -17/4
----------------
{{{graph(400,400,-10,10,-10,10,x^2+3x-2)}}}
------------------
Cheers,
Stan H.
