Question 285711
what is the domain for f(x)=3x2-18x-1 what is the function value? 
Domain: All Real Numbers.
-----------------------------------
min/max value: max at -b/2a = 18/6 = 3
f(3) = 27 - 54 -1 = -28
min at (3,-28)
--------------------- 
range::::All Real Numbers >=-28
=====================================
{{{graph(400,300,-10,10,-30,10,3x^2-18x-1)}}}
=====================================
Cheers,
