Ozzie oompah has 7 sisters and brothers. ozzie has purple hair and an orange face. in fact, all of his siblings have orange faces, but their hair color ranges form blue to purple to red. given this information, determine the genotypes and phenotypes of ozzie’s parents.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
