Ahigh school student working part-time as a cashier had a gross income of $8125 last year. if her federal tax rate was 10% and her state tax rate was 4.35%, what was the amount withheld from her pay last year in federal tax, state tax, and fica combined?

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.
