Find the domain of $f (x) = 4 x + 3$

Open in App

Solution

The domain of a function is the set of all values of $x$ which will make the function work.

The given function is $f (x) = 4 x + 3$ .

Since, there is no value that makes the function undefined, so the domain of the given function is the set of all real numbers.

Therefore, domain of $f (x) = 4 x + 3$ is ${x : x \in R}$ .
