Question

A function $f$ is defined by $f=\left\{\right(1,7),(3,5),(2,8\left)\right\}$. Then find the domain and range of $f$.

Answer 1

Given, a function $f$ is defined by $f=\left\{\right(1,7),(3,5),(2,8\left)\right\}$.

Now, domain of $f=\{1,3,2\}$.

And the range of the function $f=\{7,5,8\}$.
