Is f x x 2+1 a one to one function

WebThere are 3 methods for finding the inverse of a function: algebraic method, graphical method, and numerical method. What is the inverse of a function? The inverse of a function f is a function f^ (-1) such that, for all x in the domain of f, f^ (-1) (f (x)) = x. Similarly, for all y in the domain of f^ (-1), f (f^ (-1) (y)) = y WebYes, a function can have multiple inputs. We can graph in the coordinate plane when we have 1 input to 1 output. If we have a function with 2 inputs to create 1 output, we can graph in a 3 dimensional graph of (x, y, z). Once you go to even higher inputs, we typically would not graph them as we don't what a 4-dimensional space looks like.
