A. Write an inequality whose sign must be reversed in order to solve it. b. Write an inequality whose sign does not need to be reversed in order to solve it.
c. Explain why the sign must be reversed in Part a but not in Part b.

think about it deeply and passionately about this property

i am sorry

is means division by fractions

step-by-step explanation:

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.
