Question

Find the domain and the range of the real function, f(x)=3xx3

Open in App
Solution

We have, f(x)=3xx3

Clearly, f(x) is defined for all real values of x for which x30, i.e., x3.

dom (f)=R{3}

Let y=f(x). Then,

y=3xx3y=1, when x30

y=1, when x3

range (f) = {-1}

Hence, dom (f)=R{3} and range (f) = {-1}.
