Answer:

Figure 11. For the constant function \displaystyle f\left(x\right)=cf(x)=c, the domain consists of all real numbers; there are no restrictions on the input. The only output value is the constant \displaystyle cc, so the range is the set \displaystyle \left\{c\right\}{c} that contains this single element. In interval notation, this is written as \displaystyle \left[c,c\right][c,c], the interval that both begins and ends with \displaystyle cc.

Identity function f(x)=x.
