the graph above shows the amount an electrician charges for a job, depending on how long she works on the job. she changes a fixed amount for beginning the job plus an hourly fee. According to the graph what is the closest to the fixed amount the electrician charges for the beginning job?

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.
