graph the following function using transformations, be sure to graph all of the stages on one grph, state the domain and range y= x^2 +12x

college algebra 
Reiny
y = x(x+12)
so the xintercepts are 0 and 12
and the x of the vertex must be halfway between those intercepts
x of vertex is 6
then y = 36  6(12) = 36
vertex is ((6,36), opens up, and has xintercepts of 0 and 12
domain: obviously any value of x
range: y ≥36
