How to write domain and range of a function

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0. We can also define special functions whose

Determine Domain and Range from a Graph

For the constant function f(x)=c f ( x) = c, the domain consists of all real numbers; there are no restrictions on the input. The only output value is the constant c c, so the range is the set {c} { c } that contains this single element. In interval
