# How do you find the domain and range of #f(x) = x+2#?

##### 1 Answer

#### Explanation:

The domain of a function are those values of

If we take your example into consideration->

Here, we can let

Therefore Domain is R and Range is R.

The same cannot be said for other functions.

For example-->

Let

If there is a negative number inside the root the function will not be defined. So we apply a condition-->

Therefore

THIS IS THE DOMAIN. The value of

Now for the range, we'll put

We get

Remember the value of

So when we put any other number (bigger than

we will get values ranging till Infinity.

Therefore, the Range is
