Determine range and domain of a function
WebTo find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a … WebFind the domain and range of these functions. As usual, let’s start with relevant definitions. Definition: “If f is a function from A to B, we say that A is the domain of f and B is the codomain of f. If f (a) = b, we say that b is the image of a and a is a preimage of b. The range, or image, of f is the set of all images of elements of A.
