Best ResponseYou've already chosen the best response.1A surjective function can be even or odd or neither example even \(f:\mathbb{R}\rightarrow [0,\infty), f(x) = x^2\) is surjective and even odd \(f:\mathbb{R}\rightarrow \mathbb{R}, f(x) = x\) is surjective odd Neither \(f:\mathbb{R}\rightarrow \mathbb{R}, f(x) = 2x+3\) is neither even nor odd but is surjective

Best ResponseYou've already chosen the best response.1A function is even if \(f(x) = f(x) \) for all \(x\) A function is odd if \(f(x) = f(x)\) for all \(x\). A function is surjective if for all \(y\) there exists \(x\) such that \(f(x) = y\).

Best ResponseYou've already chosen the best response.1that is neither even nor odd. If it were even then \(f(2) = f(2)\) and it does not. If it were odd, then it would be true that \(f(2) =f(2)\) and that is not true. Check em to make sure:) It is however surjective

Best ResponseYou've already chosen the best response.1even functions are symetrical across the y axis odd functions are symetrical about the origin

Best ResponseYou've already chosen the best response.1what do you mean origin? i recently just joined this precalc class and am already having trouble lol

Best ResponseYou've already chosen the best response.1so the odd ones would look similiar to itself?

Best ResponseYou've already chosen the best response.1it means that if you flip it about the x axis and then flip it about the y axis, it looks exactly the same as when you started
