We can use linear regression model in non-linear relations in cases, where they can be expressed in linear form.

#### Explanation:

Let us assume a function such as

By taking logs of both sides, we get

As the relation is linear, we can now use linear regression model. Hence, we can do this in cases where the non-linear elation can be expressed in linear form.
