And just from an inspection, you can see that the function is not defined when x is equal to 3. You get 0 over 0. It's not defined. So to answer this question, let's try to rewrite the same exact function definition slightly differently. So let's say f of x is going to be equal to, and I'm going to think of two cases. I'm going to think of the case when x is greater than 3 and when x is less than 3. So when x is, we'll do this in two different colors actually.
