Question

Describe Domain And Range.

Answer 1

Domain and Range:

The domain of a function $f\left(x\right)$ is the set of all values for which the function is defined,

And the range of the function is the set of all values that $f$ takes.

Consider the function shown in the diagram.

Here, the domain is the set $\left\{A,B,C,E\right\}$ . $D$ is not in the domain, since the function is not defined for$D$.

Thus, The range is the set $\left\{1,3,4\right\}$ . $2$ is not in the range, since there is no letter in the domain that gets mapped to$2$ .
