What are fractions used for in real life? ⇒ ∑:

Any job that uses rates uses fractions. For example, shipping rates are determined by weight or volume of the package being measured. The rate is a fraction in units of dollars per pound or dollars per cubic inch.

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.
