If the domain is all rational numbers, then the range is all rational numbers because if y 6x is a rational number, then These wont be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. Small sets of points are generally the simplest sorts of relations, so your book starts with those. With trig functions, the domain (input values) is angle measures — either in degrees or radians. Some of the trig functions have restrictions on their domains, too.That situation happens in a function such as h(x) 3x 2. In this equation, both the domain and the range are unlimited. Domain and Range.
Functions are relation which gives us set of output corresponding to a set of inputs. While dealing with functions, students come across the two very useful concepts called domain and range. Hope this helps! you could do this without plotting the points but I find it easier If you wanted to do it this way, you know that exponential functions have an unlimited domain. Then for range, you know that an untransformed exponential function has a horizontal asymptote at y0 Date. For the parabola shown, identify the vertex, axis of symmetry, x-intercepts, maximum or minimum value of the function, and the domain and range.
