Solve for y in terms of x . Determine if y is a function of x . If it is, rewrite using notation and determine the domain.
xsquared + 12x +9=3y
f(x)=xsquared + 12x + 6=y ?

no, should be
y = (1/3)x^2 + 4x + 3
(each term had to be divided by 3)
and yes, it is a function whose domain is the set of real numbers
