1. Confirm that you have a quadratic function. A quadratic function has the form ax 2 + bx + c: f (x) = 2x 2 + 3x + 4. The shape of a quadratic function on a graph is parabola pointing up or down. There are different methods to calculating the range of a function depending on the type you are working with. A coordinate plane. The x- and y-axes both scale by one. The function f is graphed on the coordinate plane. The following points are plotted: the point negative six, one, the point zero, four, the point two, negative five, the point four, three, and the point seven, three. 4 days ago · The term domain is most commonly used to describe the set of values for which a function ( map , transformation, etc.) is defined. For example, a function that is defined for real values has domain , and is sometimes said to be "a function over the reals ." The set of values to which is sent by the function is then called the range . In mathematics, a codomain or set of destination of a function is a set into which all of the output of the function is constrained to fall. It is the set Y in the notation f: X → Y. The term range is sometimes ambiguously used to refer to either the codomain or the image of a function. A codomain is part of a function f if f is defined as a If I understand the question correctly, the range of the sequence is either $\{0,2,4,6,8\}$ or $\{2,4,6,8\}$, depending on whether your definition of natural number includes $0$; mine does, but yours may not. However, there is no way to tell what the domain is unless your textbook or instructor has established some convention. Hi there Marcus. You are simply confusing the term 'range' with the 'domain'. The x values are the domain and, as you say, in the function y = x^2, they can take any real value. However, the values that y can take (the range) is only >=0. (Notwithstanding that the y codomain extents to all real values). I hope that makes sense. Domain: ` {1, 2, 3}`. The range is the number of squares in each figure. The figures have only `1` , `5`, or `9` squares, so that’s the range. There’s no figure that has `2` or `3.5` or any other number of squares. Like the domain, the range is made of a set of discrete values. Range: ` {1, 5, 9}`. Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x x -axis. The range is the set of possible output values, which are shown on the y y -axis. Domain and Range. As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. qBlb.
