Answer:
I imagine you aren't using calculus, so:
A: the leading term is 
, so it opens upwards.
B. First coordinate of the vertex is 
, the second coordinate we'll find by replacing the value: 
C. Quadratic formula or if you stare at the equation long enough you can rewrite the equation as 
. At this point the x intercepts are the zeroes of the function, or -6 and 2.
D. The y-intercept is the value of the function at 0, or the constant term: -12
E. The graph has a minimum since the curve opens upwards.
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
-----------------------------------------------------------------------
To find the y-intercept, we set x=0 and solve for y.
Answer: -18x to the second power+3x+1
