WebEXAMPLES OF DOMAINS AND RANGES FROM GRAPHS Important notes about Domains and Ranges from Graphs: Remember that domain refers to the x-values that are represented in a problem and range refers to the y-values that are represented in a problem. Sometimes it isn’t possible to list all the values that x or y can be because the … 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.

WebOne way to include negatives is to reflect it across the x axis by adding a negative y = -x^2. With this y cannot be positive and the range is y≤0. The other way to include negatives is to shift the function down. So y = x^2 -2 shifts the whole function down 2 units, and y ≥ -2. Comment. Button navigates to signup page.
