Find the domain of the function. (enter your answer using interval notation.) f(x) = x + 4 x2 − 36

Alright, lets get started.

The given function is :

When we find the domain of any function, we consider the domian is set of input values for which function should remain real and defined.

In this given function , we have not given any points where function seems going undefined.

Hence the domain is : (-∞, +∞) : Answer

Hope it will help :)
