ohhhhhhh. wtf. i don't get why they have put this in an assignment if they haven't even taught us it and it isn't in the textbook.

LOL I'm not even sure how to do that. Ill give it a shot, in F do I swap the function around so I have an expression for x and y, then substitute in the value for x and the value for y into B... if so would it look something like this... B(F(x,y))= sqrt(1-y^2) +3*sqrt(1-x^2) +3=0 ?

Homework Statement Denote the xy plane by P. Let C be some general curve in P defined by the equation f ( x , y ) = 0 where f ( x , y ) is some algebraic expression involving x and y. Verify carefully that if B : P -> P is any bijection then B( C ) is defined by the equation f ( B^-1...
