WebTesting whether it is onto : Range of f = co-domain If f : A -> B is an onto function then, the range of f = B . That is, f (A) = B. Let x ∈ A, y ∈ B and x, y ∈ R. Then, x is pre-image and y is image. Then, we have y = 2x + 1 Solve for x. x = (y - 1) /2 Here, y is a real number. WebI understand that f from A to B is called onto if for all b in B there is an a in A such that f ( a) = b. All elements in B are used. Thus, the function f ( x) = 3 x − 4 is onto where f: R → R. Here we can get all real values of f ( x) for real values of x. So, this function is an onto function. We would like to show you a description here but the site won’t allow us.
