Well, first, let's explain what a domain and range is A domain is the set of argument values (or "input") in which the function is defined So, for example for a function #g(x) = sqrt(x)#, the domain will be all nonnegative real numbers, or #x >= 0# For this function #f(x)#, we see that the function has no square roots, fractions, or logarithmic functions that would be undefined forFirst week only $499!The Domain and Range of a Function The domain of a function is the set of values for the variable in which the function is defined or real On the

A function would have at least two sets, and it can either be the domain or range Earlier in the introduction, these are The set of all possible input values is the domain The set of all possible output values is the rangeDomain and range graph The graph of f(x)=x2 f ( x) = x 2 (red) has the same domain (input values) as the graph of f(x)=− 1 12x3 f ( x) = − 1 12 x 3 (blue) since all real numbers can be input values However, the range of the red graph is restricted to only f(x)≥0 f ( x) ≥ 0, or y y values above or equal to 0 0For the cubic function latexf\left(x\right)={x}^{3}/latex, the domain is all real numbers because the horizontal extent of the graph is the whole real number line The same applies to the vertical extent of the graph, so the domain and range include all real numbers

The given real function is f (x) = x − 1 It can be seen that x − 1 is defined for (x − 1) ≥ 0 ie, f (x) = (x − 1) is defined for x ≥ 1 Therefore the domain of f is the set of all real numbers greater than or equal to 1 ie, the domain of f = 1, ∞)Hence, for the trigonometric functions f (x)= sin x and f (x)= cos x, the domain will consist of the entire set of real numbers, as they are defined for all the real numbers The range of f (x) = sin x and f (x)= cos x will lie from 1 to 1, including both 1 and 1, ie 1 ≤ sin x ≤1
